Answer:
-4.67
Step-by-step explanation:
first find f^-1(x)
let f(x)=y
y=3x+2
3x=y-2
x=y-2/3
Therefore f^-1(x)=x-2/3
Now f^-1(-12)=-12-2/3
=-14/3
=-4.67
Triangles MNP & MAB are similar (NP//AB & Angle A= Angle N (correspondent) Same for P & B
We know that MA = 67.2 -3.2 = 35.2
Since Triangles MNP & MAB are similar , then we can write the following ratio:
MN/MA=MP/MB or 67.2/35.2 =81.9/x
& x= 43 m
Answer:
7 x 7 x 8 = 392
15 x 7 x 7(14 - 7) = 735
735 + 392 = 1,127 in^3 is your answer.
Let's split the figure:
Answer:
Step-by-step explanation:
X^2 + 7x + 7x + 49 = x*(x+7) + 7*(x+7) = (x+7)(x+7) = (x+7)^2
