The length of the hypotenuse = sqrt(4^2 + 6^2) = sqrt(52) = 2 sqrt13 inches.

20. Find the value or values of y in the quadratic equation y2 + 4y + 4 = 7. A. y=2,y=7 C. y=–2 7,y=2 7 B. y=2+2 7,y=2–2 7 D. y=–2+ 7,y=–2– 7
Weegy: 1 User: 6. Which of the following are the factors of q3 – q2 + 2q – 2? A. (q2 –1)(q+2) B. (q–1)(q2 +2) C. (q–1)(2–q) D. (q–1)(2–q2) (More)
Question
Updated 4/10/2014 8:07:49 PM
y^2 + 4y + 4 = 7
y^2 + 4y - 3 = 0
a = 1, b = 4, c = -3
b^2 - 4ac = 4^2 - 4(1)(-3) = 28
y = (-4 + sqrt28)/2 = -2 + sqrt 7
or y = (-4 - sqrt28)/2 = -2 - sqrt 7

q^3 – q^2 + 2q – 2
= q^2(q - 1) + 2(q - 1)
= (q - 1)(q^2 + 2)
