Answer: 57 inches

Step-by-step explanation: For the area to be 25 square feet , each side would have to be 5 feet. Convert 5 feet to inches. Each side would be 60 inches. If the original square’s side length was 3 inches less, it would be 60-3= 57 inches.

$470 is raised by 30%. What is the value after the increase?
alekssr [168]
<h3>Answer:  $611</h3>

Work Shown:

30% of 470 = 0.30*470 = 141

The value goes up by $141, so the answer would be 470+141 = $611

A slight shortcut would be to say

1.30*470 = 611

This works because 1.30 = 1 + 0.30 = 100% + 30%

Given f(x)=2x^3-3x and g(x)=-3x^2+1, what is the value of h(3) where h(x)=(f+g)(x)?
Mamont248 [21]

Answer:

h(3) = 73

Step-by-step explanation:

The function h(x) = f(x) + g(x) = 2x^3 -3x +3x^2 +1 = 2x^3 +3 x^2 -3x+1

Now since you need to find the value of this new function at the point x=3, replace x by "3" in the expression above and perform the calculation:

h(3) = 2(3)^3 +3 (3)^2 -3(3)+1=73

Write the equation in slope-intercept form of the line passing through (2,7) and (-5,2).
sasho [114]

Hello!

Explanation:

Slope-intercept form: → y=mx+b

m: represents the slope and is constant.

b: represents the y-intercept.

Rise/run.

m=\frac{rise}{run}

x^1,y^1=(2,7)

x^2,y^2=(-5,2)

\frac{2-7=-5}{(-5)-2=-7}= \frac{-5}{-7}

\frac{-5}{-7}=0.714

<u><em>Y-intercept is -7</em></u>

<u><em>But the slope is -5.</em></u>

<u><em>Answer: → 0.714</em></u>

Hope this helps!
