Answer:

X = -4 , x= 4

Step-by-step explanation:

20=x^2-x=0

-20+x^2+x=0

x^2+x-20=0

x×(x+5)-4(x+5)=0

(x+5)×(x-4)=0

x+5=0

×-4=0

x=-5

x=4

Solve for L:<br> P=2L+2W
Korvikt [17]

Answer:

L=\frac{1}{2}P-W

Step-by-step explanation:

Let's solve for L.

P=2L+2W

Step 1: Flip the equation.

2L+2W=P

Step 2: Add -2W to both sides.

2L+2W+-2W=P+-2W

2L=P-2W

Step 3: Divide both sides by 2.

\frac{2L}{2}=\frac{P-2W}{2}

L=\frac{1}{2}P-W

Answer:

L=\frac{1}{2}P-W

What is the answer to this question can you please answer right
Arada [10]
On Monday she made 50 throws.
On Tuesday she made 56 throws.

a) The increase is just how much more she made the next day.
56 - 50 = 6
She had an increase of 6 free throws.

b) To find the percent increase, all you do is divide the two numbers.
56/50 = 1.12
To change that into a percentage, either multiply it by 100 or move the decimal point two places to the right.
1.12 × 100 = 112
She had a 112% increase in her free throws.

The answer is:
D. 6; 112%
