Answer:
x^158
Step-by-step explanation:
x^12^5 is x^60
x^-2^9 is x^-18
x^60*x^-18 = x^60-18=x^42
x^40^5 is x^200
x^42 *x^y=x^200
200-42 is 158
y=158.
The blank is x^158.
Hope this helps plz hit the crown :D

Answer:
average = 52, 100 on fourth test
Step-by-step explanation:
average = 75 + 74 + 71 = 156 / 3 = 52
average = 52
b grade = 75 + 74 + 71 + 100 = 320 / 4 = 80
to get a b grade she must get 100 on her fourth test
Answer:
t = 6
Step-by-step explanation:
Because you need to transfer the 64 to the other side dividing and the operation will be t = 384 / 64
Let the solutions be a and b.
a = -2; b = -10
a + b = -2 + (-10) = -12
ab = (-2)(-10) = 20
(x - a)(x - b) = 0
(x - (-2))(x - (-10)) = 0
(x + 2)(x + 10) = 0
x^2 + 10x + 2x + 20 = 0
x^2 + 12x + 20 = 0
-h = 12
h = -12
4k = 20
k = 5
