Answer:
(3x + 5)^2 expands into two binomials: (3x + 5)(3x +5)
from there, you foil them:
(3x + 5)(3x + 5)
multiply the first terms ... 9x^2
the inside terms ... 9x^2 + 15x
outside terms ... 9x^2 + 15x + 15x
last terms ... 9x^2 + 15x + 15x + 25
then add like terms ... 9x^2 + 30x + 25
Answer:
v = 1
Step-by-step explanation:
-6(9-9v)
-6*9 = -54
-6*(-9v) = 54v
-54+54v = 0
+54 +54
54v = 54
divide both sides by 54
v = 1
Answer:
<h2>
B. 9</h2>
Step-by-step explanation:
|<-------------- 27 ------------>|
L--------------M----------------N
18 MN
LN = LM + MN
27 = 18 + MN
MN = 27 - 18
<h2>
MN = 9</h2>
It would be 40 because it adds the sum of the equation before it
