We can split into factors using the "guess and check" method.
Factors are in the format of:
(ax + b)(cx + d), where in this instance:
a · c = 2
bc + da = 5
b · d = 3
Thus, we get:

Answers
Answer:

Step-by-step explanation:
The equation of x has No solution.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions by connecting them with the equal sign = .
Now the given equation is,
−3x − 3 = −3(x + 1)
Expanding the brackets we get,
−3x − 3 = −3x − 3
Collecting like terms together we get,
−3x + 3x = −3 + 3
Solving we get,
0 = 0
So, this equation has no solution.
Thus, the equation of x has No solution.

Answers
Answer:

100 = 15 + 5h
Subtract 15 from each side
100-15 = 5h
85 = 5h
Divide by 5
85/5 = 5h/5
17 =h
Answer:
Kim rent the bike for 17 hours.
Step-by-step explanation:
h=hours
15 + 5h = 100
Subtract 15 on both sides.
5h = 85
Divide 5 on both sides.
h = 17

If ∠MOK and ∠JOM are supplementary angles, then what is the value of x and m∠LOK?
A.
x = 130; m∠LOK = 66°
B.
x = 50; m∠LOK = 114°
C.
x = 114; m∠LOK = 50°
D.
x = 66; m∠LOK = 130°
Answers
Answer:
B
Step-by-step explanation:
Note that angle JOM and angle LOK are vertical angles meaning that they are congruent ( equal to each other )
We are given that angle MOK and angle JOM are supplementary
Supplementary angles add up to 180
This means that:
angle MOK + angle JOM = 180
If angle JOM = angle LOK
Then angle MOK + angle LOK also = 180
If angle MOK = 66 and angle LOK = x + 64
Then 66 + x + 64 = 180
Note that we've just created an equation that we can use to solve for x
We now solve for x
66 + x + 64 = 180
Combine like terms
66 + 64 = 130
130 + x = 180
Subtract 130 from both sides
x = 50
We also want to find the measure of angle LOK.
To do so we simply plug in the value of x into x + 64
angle LOK = x + 64
x = 50
angle LOK = 50 + 64 = 114
So x = 50 and angle LOK = 114

Answers
Answer:
3 = - 4g - 5
3 + 5 = - 4g
8 = - 4g
8/-4 = g
-2 = g

The value of g in the equation 3= −4g −5 is -2.
What is Equation?Two or more expressions with an Equal sign is called as Equation.
The given equation is 3=-4g-5
Three equal to minus four times of g minus five.
The g in the equation is a variable.
The operator in the given equation is Subtraction which is minus.
We need to find the value of variable g.
By addition property add 5 on both sides
3+5= −4g −5+5
The plus five and minus five will be cancelled in the right side.
3+5=-4g
Add 3 and 5 in left side.
8=-4g
By division property divide both sides by 4
g=-2
Hence, the value of g in the equation 3= −4g −5 is -2.

Answers
Answer:
Angle 1 is 22°
Angle 2 is 78°
Step-by-step explanation:
Angles on a straight line always add up to 180°.
To find Angle 2, you would have to do 180° take away 102°.
180-102=78°
Angles in a triangle also add up to 180°.
So to find Angle 1, you would have to add the two Angles you already have and take it away from 180°.
