Answer:
9
18
Step-by-step explanation:
<u>x = 2:</u>
4(4 + 2 - 3) - 6 + 3 = 12 - 6 + 3 = 9
<u>x = 3:</u>
4(6 + 3 - 3) - 9 + 3 = 24 - 9 + 3 = 18
Answer:
14
Step-by-step explanation:
(I go to a french school, so excuse my terminology, which might not always be correct)
The angle we can see, in GHI, is equal to 121°. JKL has an identical angle, meaning JKL is an enlargement (probably the wrong term, I apologise) of GHI. This means we can use the length of it's sides to find KL.
GH and GI are both multiplied by two (GH = 4 becomes JK = 8, GI = 5 becomes JL = 10) meaning you must multiply HI by 2 to find KL.
2*7 = 14
KL = 14

Answer:
x = 10
Step-by-step explanation:
-8(-3 + x) = -56
Distribute the -8 into the (-3 + x).
24 - 8x = -56
Subtract 24 from both sides.
-8x = -80
Divide both sides by -8.
x = 10.
Proof:
-8(-3 + x) = -56
Substitute variable.
-8(-3 + 10) = -56
Add inside parenthesis.
-8(7) = -56
Multiply.
-56 = -56
