2/3A=-24 <br><br> this the last one that I need help on.
pychu [463]
You can answer this question in numerous ways but one simple way is by multiplying fractions. 

<span>2/3 of 24 is also 2/3 of 24/1 </span>
<span>To get the answer, you must multiply 2/3 by 24/1 </span>

<span>To do this, you multiply the numerator (the top number) by the other numerator. That is, 2 x 24 . The answer is 48. </span>

<span>Then, multiply the denominators (the bottom numbers) by each other. That is, 3 x 1. The answer is 3. </span>

<span>The answer is 48/3. But you must continue simplifying. </span>

<span>What is 48 divided by 3? 16. </span>

<span>If you do not understand it that way, think of it in a simpler way. </span>

<span>Say there are 24 slices of pieces. </span>

<span>What is one third of those 24 slices? </span>

<span>24 divided by 3 = 8. </span>

<span>Now you want TWO thirds. So all you do is multiply 8 by 2. </span>

<span>That gives you 16.

The height of a triangle is 4 feet more than 3 times the base. If the area is 112 ft find the base and height of the triangle
Finger [1]

Answer:

base = 8 ft\\height =28 ft\\

Step-by-step explanation:

let base be x ft. then the height is 3x+4

Area=\frac{1}{2} \times x  \times (3x+4)=112\\3x^{2} +4x=224\\3x^{2} +4x-224=0\\x=8, x=-9.33 (no sol. as length can not be negative)\\ x=8\\base = 8 ft\\height =3(8)+4=28 ft\\

Solve 5n^2=5 with the quadratic formula
Yanka [14]

Answer:

n = 1

Step-by-step explanation:

First, rearrange the equation to standard form 0 = ax² + bx + c, when everything equals 0.

5n² = 5

5n² - 5 = 0

State the variables a, b and c.

a = 5;  b = 0;  c = -5

Substitute a, b, and c into the quadratic formula.

n = \frac{-b ±\sqrt{b^{2}-4ac} }{2a}

n = \frac{-0 ±\sqrt{0^{2}-4(5)(-5)} }{2(5)}   Substitute

n = \frac{\sqrt{100} }{10}   Simplify inside the √ and bottom

n = \frac{10}{10}  Simplify the top

n = 1  Final answer

Therefore the solution is n = 1.

The quadratic formula usually is written with x, but it can be solved with any variable in standard form.
