The answer to your question is A
Answer:
357
Step-by-step explanation:
A) We replace x = - 5 and u = 3 into -3x^3 -2y^2
and we have -3x^3 -2y^2= -3*(-5)^3 -2*3^2= -3*(-125)- 2*9
or -3x^3 -2y^2 = 375-18= 357
The answer is 357.
B) Replace h = -2 into h^2-3h+2
we have h^2-3h+2 = (-2)^2 -3*(-2) +2 = 4 +6 + 2= 12
The answer is 12
Have a good day.
2 square root x • 4x= 22
2x=22
x=11
Answer is 11
2x+1 = x-5
-x -x
X+1 = -5
-1 -1
X = -6
2(-6) +1= y
-12+1= y
-11 = y
-11 = -12+1
-11 = -6-5
