What is the product? assume x>0 (√3x + √5) (√15x +2√30

Answers

Answer 1

Answer: The first step for solving this expression is to multiply the parenthesis.
$√(45) x^(2) + 2√(90) x + √(75)x + 2√(150)$
Simplify the first radical.
$3√(5) x^(2) + 2√(90) x + √(75)x + 2√(150)$
Simplify the second radical.
$3√(5) x^(2) + 2X3√(10) x + √(75)x + 2√(150)$
Simplify the third radical.
$3√(5) x^(2) + 2X3√(10) x + 5√(3)x + 2√(150)$
Simplify the final radical.
$3√(5) x^(2) + 2X3√(10) x + 5√(3)x + 10√(6)$
Lastly,, calculate the product of 2 × 3 $√(10)$ x to get your final answer.
$3√(5) x^(2) + 6√(10) x + 5√(3)x + 10√(6)$

Answer- y=-9+5

Answer:

y = -9x +5

Step-by-step explanation:

y = mx+b

x = what you multiply the slope by

b (y-int) = the y-intercept

y = y
