Question

Evaluate the following expression using the values given.

Find 2x2 - 2z4 + y2 - x2 + z4 if x = -4, y = 3, and z = 2.

Answer 1

well @jose7895 did you solve your last question?

Answer 2

i helped you how to solve.you can use it here and solve this question.

Answer 3

can you help me solve this one as well? @PFEH.1999

Answer 4

well,you have x = -4 so what is (2)x^2 ?

Answer 5

first find x^2 and then you can find 2(x^2)

Answer 6

2(x^2)=-16

Answer 7

but x= -4 so x^2 = (-4)(-4) = 16 and 2x^2 is 32

Answer 8

ok

Answer 9

sty i have to go you can do it for the rest and find the values:
2x2
2z4
y2
x2
z4
and then you can solve it easily

Answer 10

2x2 = 32
2z4 = (2)2^4 = 64
y2 = 3^2 = (3)(3) = 9
can u do the rest?
