Answer:
9√2
Step-by-step explanation:
expression: √8 + 3√2 + √32
Simplify so all constants are by √2: <em>2√2 + 3√2 + 4√2</em>
Combine like terms: 9√2
9sqrt2.
sqrt8 + 3sqrt2 + sqrt32
= sqrt4 * sqrt2 + 3 sqrt2 + sqrt16 * sqrt2
= 2sqrt2 + 3sqrt2 + 4 sqrt2
= 9 sqrt2.
f(-2) = -1
-2 is x, so replace x as -2 into the equation
f (-2) = 2(-2) + 3
f (-2) = -4 + 3
f (-2) = -1
