Question

Evaluate
a.30-2x for x=-6
b.x to the power of two + 2x for x=-3​

Answer 1

30-2x evaluates to 42

x^2+2x evaulates to 9

Further explanation:

In order to evaluate the expression on a given value the value is put in place of variable in the expression

So,

a.30-2x for x=-6

$30-2x\\=30-2(-6)\\=30+12\\=42$

b.x to the power of two + 2x for x=-3​

$x^2+2x\\=(-3)^2+2(-3)\\=9-6\\=3$

Hence,

30-2x evaluates to 42

x^2+2x evaulates to 9
