Answer: C) (x + 5i)(x - 5i)
<u>Step-by-step explanation:</u>
x² + 25 can be rewritten as x² - (-25)
Now use the difference of squares to factor: a² - b² = (a + b)(a - b)
√x² = x √-25 = 5i
--> x² + 25 = (x + 5i)(x - 5i)
Answer:
c = 121
Step-by-step explanation:
Given
t² - 22t
To complete the square
add ( half the coefficient of the t- term )² to t² - 22t
= t² + 2(- 11)t + (- 11)²
= t² - 22t + 121
with c = 121
Thus
t² - 22t + 121 = (t - 11)²
Answer:
s= 2( lw + hw+ hl)
298
Step-by-step explanation:
w = 8inched
l=12inches
h=4inches
s = 2 ((12×8)+(4×8)+(4×12))
=2 (96+32+48)
= 2 (149) =298
