Answer:
37
Step-by-step explanation:
Let's use the rule GEMDAS (Grouping, Exponents, Multiply, Divide, Add, Subtract) from left to right. Therefore, we will simplify the equation in the parentheses. . -(-7) creates a double negative, deeming the 7 positive, because when there is two negatives the number will turn into a positive.
= 49, -3 x 4= -12. Therefore the final form of the equation will be 49 - 12 = 37.

Answer:
(12, 6 )
Step-by-step explanation:
To find M use the Section formula
=
=
= 12
=
=
= 6
M = (12, 6 )
Answer:
<h2>x = 7</h2>Step-by-step explanation:
ΔKLJ and ΔNPM are similar (Angle-Angle). Therefore the sides are in proportion:
We have:
MP = 4x - 4
JL = 20
MN = 30
JK = 25
Substitute:
<em>cross multiply</em>
<em>use distributive property</em>
<em>add 100 to both sides</em>
<em>divide both sides by 100</em>
