Answer:

x^4+3x^3-9x^2-12x+20

Step-by-step explanation:

Use the distributive property to multiply x^2−4 by x^2+3x-5 and combine like terms.

Answer:

Step-by-step explanation:

Given polynomial:

Convert this into standard form, order in descending powers:

The leading term, -2x⁹ is the one with the greatest power. Its coefficient, -2 is the leading coefficient.

[tex]\\ \rm\longmapsto 3x^6-2x^9+5x-12[/tex]

Write in standard form

[tex]\\ \rm\longmapsto -2x^9+3x^6+5x-12[/tex]

-2x has greatest degree hence leading coefficient is -2.

Answer:

-58, -57, -56

Step-by-step explanation:

if the first integer is x,

the second integer must be x + 1 (because it's consecutive)

and the third must be x + 2

Therefore:

3 times the sum of the first and third integers is -342:

3 * (x + (x+2) ) = -342

Combine like terms in parentheses

3 * (2x + 2) = -342

Distribute the 3 to the 2x and the 2:

6x + 6 = -342

Subtract 6 on both sides

6x = -348

Divide by 6 on both sides

x = -58

x + 1 = -57

x + 2 = -56

-58, -57, -56

Check:

3 * (-58 + -56) = 3 * -114 = -342

Answer:36 times for 8 dollars

Step-by-step explanation:

k so first you divide 54 and 12 =4.5 per dollar so you then multiply 4.5 and 8 to get the answer that =36 times for 8 dollars

Answer: Third Choice. B,C, and E

Concept:

A scaled copy is a copy of a figure where every length in the original figure is multiplied by the same number.

Explanation:

Choice A. [tex]\boxed{FALSE}[/tex]

The figure given as choice A seems to be much thinner than the original image. Therefore, the figure did not copy each length in scale.

Choice B. [tex]\boxed{TRUE}[/tex]

The figure given as choice B seems to be the same size as the original image but different position. However, the position is not a concern in a scaled copy image. Therefore, the figure did copy each length in scale.

Choice C. [tex]\boxed{TRUE}[/tex]

The figure given as choice C seems to be larger than the original image and different position. However, the scale of choice C seems even to the original image. Therefore, the figure did copy each length in scale.

Choice D. [tex]\boxed{FALSE}[/tex]

The figure given as choice D seems to be larger and wider than the original image. Therefore, the figure did not copy each length in scale.

Choice E. [tex]\boxed{TRUE}[/tex]

The figure given as choice E seems to be smaller than the original image and different position. However, the scale of choice C seems even to the original image. Therefore, the figure did copy each length in scale.

Therefore, the choices would be B, C, E, which would be the third choice.

Extra: A shortcut (lazy) way to do the question

As listed above, A and D are clearly not to scale since one is much thinner, one is much wider. Therefore, we can directly neglect choices that contain A and D, which would only leave us with the third choice.

Hope this helps!! :)

Step-by-step explanation:

Hi, there I hope you are having a great day :) your question Kevin plays on the school baseball team. In the last 8 games, Kevin was at bat 30 times and got 7 hits. What is the experimental probability that Kevin will get a hit during his next time at bat?

1. In the last 8 games the total number of Kevin was at the bat was 30 and the number of times in which he hit the ball was 7.

2. Now we do the experimental probability = P (Hit) = Number of hits divided by the number of Kevin at the bat.

3. So the answer would be 7/30

Hopefully, that helps you :)

No

Step-by-step explanation:

The calculator isn't water or a fluid, therefore you have to follow the dimesions by the question. Since the Calculator is 14cm by 12.5cm, and the pencil case is 20cm by 10cm, the calculator cannot simply fit inside the pencil case as the calculator's width is longer than the pencil case's width. We do not include the height in this question as the pencil case's height is not included

Answer:

Step-by-step explanation:

Red = 8

Green = 6

Blue = 14

Total = 8+6+14 = 28

(a) Proability of drawing a green bead = 6/28 = 3/14

Answer for (a) = (iv)

(b) Probability of drawing beads that are not green = 8+14/28

                                                                                     = 22/28

                                                                                     = 11/14

Answer for (b) = (iii)

(c) Probability of drawing green or blue beads = (6/28) + (14/28)

                                                                             = (3/14) + (1/2)

                                                                             = 5/7

Answer for (c) = (i)

(d) Probability of drawing (not red and not green beads) = 1 - p(red) -p(green)

                                                                                              = 1 - 8/28 - 6/28

                                                                                              = 1 - 2/7 - 3/14

                                                                                              = 1/2

Answer for (d) = (iv)

Answer for (e) = (iv)

Answer:

2x^11

Step-by-step explanation:

distributing x^8(2x^3) makes 2 * x^3 * x^8. To multiply exponents, just add the powers together to make 11. This makes 2x^11.

Answer:

[tex]8x^1^1[/tex]

Step-by-step explanation:

Hi there!

[tex]x^8*(2x)^3[/tex]

Distribute the exponent into the parentheses:

[tex]= x^8*2^3x^3\\= x^8*8x^3\\= 8*x^3*x^8[/tex]

When two powers have the same base, add the exponents:

[tex]= 8*x^3^+^8\\= 8*x^1^1\\= 8x^1^1[/tex]

I hope this helps!
