Answer:
161
Step-by-step explanation:
It's a system of equations, let's solve it step-by-step!
Equation: [3 * 2^5 + 13 * (-2)] + 7[8 - (4 - 9)]
2^5 = 32
so we have [3 * 32 + 13 * (-2)] + 7[8 - (4 - 9)].
3 * 32 = 96
so we have [96 + 13 * (-2)] + 7[8 - (4 - 9)].
13 * (-2) = -26
so we have [96 - 26] + 7[8 - (4 - 9)].
96 - 26 = 70
so we have 70 + 7[8 - (4 - 9)].
4 - 9 = -5
so we have 70 + 7[8 - (-5)].
8 - (-5) = 13 (the signs cancel out)
so we have 70 + 7[13].
7 * 13 = 91
so we have 70 + 91.
70 + 91 = 161
Therefore our answer is 161.

What is Geometry?It deals with the size of geometry, region, and density of the different forms both 2D and 3D.
The length of the kite (x) will be given by the Pythagoras theorem
H² = P² + B²
H² = 15² + 8²
H² = 225 + 64
H² = 289
H = 17
Then
[tex]\rm x = \dfrac{H}{2} \\\\x = \dfrac{17}{2}\\\\x = 8.5[/tex]
And another length of the kite is 5 units.
Then the perimeter of the kite will be
Perimeter = 2(8.5 + 5)
Perimeter = 27

a) 8, 10, 12
b) 8, 16, 32
c) 2, 16, 128
d) 2, 10, 18
Answers
The sequence an=an−1+2 is an arithmetic sequence
The first three terms in the sequence are (a) 8, 10, 12
How to determine the first three terms?The sequence is given as:
an=an−1+2
Where:
a1 =8
Start by calculating a2 using:
a2=a1+2
This gives
a2=8+2 = 10
Calculate a3 using:
a3=a2+2
This gives
a3=10+2 = 12
So, we have:
a1 = 8, a2 = 10 and a3 = 12
Hence, the first three terms in the sequence are (a) 8, 10, 12

Answers
The magnitude of the force of 34.64 is more than the magnitude of the force of 24.75. The direction of the force is on the 34.64 sides.
What is force?The product of mass and its acceleration is known as force.
Two students are pulling an object with ropes. one student pulls with a force of 40 pounds at an angle of 30° above the ground, and the other student pulls with a force of 35 pounds at an angle of 45° above the ground.
Then the direction of the force will be
→ 40 × cos 30° = 34.64
→ 35 × cos 45° = 24.75
Then
34.64 - 24.75 = 9.89
Then the direction of the force is on the side of 40 pounds.

A figure is composed of two cubes. The side lengths of the larger cube are twice the side length of the smaller cube. If the total volume of the cubes is 1,944 m3, what are the side lengths of the two cubes? Enter the smaller dimension first
Answers
The side lengths of the two cubes are 6 meters and 12 meters respectively.
How to calculate the volume of a cube?Mathematically, the volume of a cube is calculated by using this following formula:
Volume = m³
Where:
m is the side lengths of a cube.
Translating the word problem into an algebraic expression, we have;
m³ + (2m)³ = 1944
m³ + 8m³ = 1944
9m³ = 1944
m³ = 1944/9
m = ∛216
m = 6 meters.
For the bigger cube:
2m = 2 × 6
2m = 12 meters.

Which of the following is a Pythagorean triple?
Answers
just plug those numbers in a Pythagorean theorem equation to see if they are triples
Answer:
C: 8, 15, 17
Step-by-step explanation:
The easiest way to do this is simply to memorize the first few Pythagorean triples. It saves time. But it can also be hard to remember that. To see if something is a triple...
1. [tex]a^{2} + b^2=c^2[/tex]. This means square the first one, the second and add. Then square the last one. The sum of the first two with the last one should be the same.
2. For this to work, they have to be in order from least to greatest. All of these are.
3. Let's fill in the equation:
8^2= 64.
15^2= 225.
225+64= 289
17^2= 289.
It matches! It's a triple.

What is a quadratic equation?A quadratic equation is the second-order degree algebraic expression in a variable. the standard form of this expression is ax² + bx + c = 0 where a. b are coefficients and x is the variable and c is a constant.
A function f(x) has x-intercepts of –3 and –5 means
f(x) = (x+3)(x+5)
f(x) = a(x + 3)(x + 5), here a is a multiplier
let a = 1 then
f(x) = (x + 3)(x + 5) (expand factors)
f(x) = x² + 8x + 15
thus, 15 is the constant term
