I will do the first one only. The second question is done the same way.
Replace every x you see in the function with 2b and do the math.
f(x) = x^2 + 2x + 1
Let x = 2b
f(2b) = (2b)^2 + 2(2b) + 1
f(2b) = 4b^2 + 4b + 1
Did you follow? That's all there is to it.
Note that (-6)^2 = (-6)(-6)
Multiply across. Remember that when multiplying two negative numbers, the product would be a positive answer
(-6) x (-6) = 36
36 is your answer

The answer for the first question: C The rotated image may be larger than the original image.
Answer:
y = 36
Step-by-step explanation:
The two angles are supplementary since they are same side exterior angles
74 + (2y+34) = 180
Combine like terms
2t+108 =180
Subtract 108 from each side
2y = 180-108
2y = 72
Divide by 2
2y/2 = 72/2
y =36
1 yd = 3ft
52 ft = 17 +1/3 yards
she must by 18 yards as the only sell by yard, not feet.
18 x 10.99
197.82
