Answer:
D) Jack made a mistake while squaring first term, 16x^2 - 8x +1
Step-by-step explanation:

we apply (a-b)^2 formula

a= 4x and b= 1
Replace 'a' with 4x and 'b' with 1

(4x)^2 is 16x^2

Jack made a mistake while squaring first term
(4x)^2 is 4^2x^2 that is 16x^2
Answer:
Step-by-step explanatinon:
percent is per hundred
4 dimes is 40 cents or $0.40 or 40/100 of a dollar which is40%
1 nickel and 3 pennies or 8 cents or $0.08 Or 8/100 or 8%
5 quarters and one dime is 135/100 or $1.35 or 135/100 which is 135%
Answer:
36
Step-by-step explanation:
2x is an exterior angle
Exterior angles = the sum of the two remote (unconnected - non supplementary interior angles).
Put symbolically
<LEG = <EGF + <EFG
<EFG = 180 - 4x In this case you need to find the supplemtnt
<LEG = x + 180 - 4x
2x = 180 - 3x Add 3x to both sides
5x = 180 Divide by 5
x = 36
5 times the Sum of 3 and 4, then subtract 4
