W-1/4= 3/7
W-1/4+1/4= 3/7+1/4
find the common denominator for the fractions
common denominator is 28
Multiply by 4 , top and bottom for 3/7
Multiply by 7 , top and bottom for 1/4
W= 12/28+7/28
W= 19/28
Answer is W= 19/28

Answer:
B. x = -6, x = 4
Step-by-step explanation:
The constant on the left wants to be 1, the square of half the x-coefficient. We can get it to be that value by adding 8 to the equation.
x² +2x +1 = 25
(x +1)² = 25 . . . . . . . rewrite the left side as a square
x +1 = ±√25 = ±5 . . . . take the square root
x = -1 ±5 . . . . . . . . . subtract 1
x = -6 or x = 4
Answer:
Length of QR = 7
Step-by-step explanation:
20 - 13 = 7
Answer:
B
Step-by-step explanation:
So far, we know that:
∠D = ∠J.
And that:
DE:JK = 14:7 = 2:1
So, to prove that ΔDEF ~ ΔJKL by SAS, DF must be similar to JL, as those are the sides between the angle.
So:
DF:JL = 2:1.
Our answer is B.
