You just plug in the values.

[3*(-2)]^3 - (-2 - 4*5)^2

(-6)^3 - ( - 2 - 20)^2

-216 - (-22)^2

-216 - (484)

Find the value of X
vredina [299]

Answer:

x=8

RPS = 36

Step-by-step explanation:

QPS = 180

The two angles that form QPS

QPR + RPS = 180

7x+88 + 3x+12 = 180

Combine like terms

10x+100 =180

Subtract 100 from each side

10x = 180-100

10x = 80

Divide by 10

x =80/10

x = 8

RPS = 3x+12

        = 3(8)+12

         24+12

        36

Subtract 1 3/4 from 2 7/10. please answer me now I want it immediately ​
Andrei [34K]

Answer:

Rewriting our equation with parts separated

=1+3/4−2−7/10=1+3/4−2−7/10

Solving the whole number parts

1−2=−11−2=−1

Solving the fraction parts

3/4−7/10=?

Find the LCD of 3/4 and 7/10 and rewrite to solve with the equivalent fractions.

LCD = 20

15/20−14/20=1/20 15/20−14/20=1/20

Combining the whole and fraction parts

−1+1/20=−19/20

Given f(x) = −9x5 − x4 + 3x3 − 8 and g(x) = −9x5 − 3x3 − 9x2 + 7, find and simplify f(x) − g(x)
KatRina [158]
F(x) − g(x) =  −9x^5 − x^4 + 3x^3 − 8 − (<span>−9x^5 − 3x^3 − 9x^2 + 7)
</span>f(x) − g(x) =  −9x^5 − x^4 + 3x^3 − 8 + 9x^5 +  3x^3 +  9x^2 −  7
f(x) − g(x) = − x^4 + 6x^3 +  9x^2 - 15
hope it helps
