Answer:

x=3. x= -7

Step-by-step explanation:

-4|X+2|= -20

1. divide equation by -4

| x+2 | = 5

2. subtract 2

x= 5

3. X+ 2 = -5

subtract 2

x equals -7

4. plug both X's into the equation and check if the answer is true ( they are).

Find the perimeter of the right triangle.
Contact [7]

Answer:

b. 36

Step-by-step explanation:

You have to use Pythagorean theorem. A squared + b squared = c squared.

a=12    12^2 (12 squared)= 144

b=9      9^2 (9 squared)= 81

144+81=225

Then you find the square root of 225 which is 15. Since you have the length for side c.

12+9+15=36

7. How many servings could you make if you had 3/4 cup of diced onion?
jekas [21]

Answer:

D. 12 servings

Step-by-step explanation:

Normally, when working with fractions, I would like to make the denominators of both fractions the same.

\frac{1}{2} cup diced onion --- 8 servings

\frac{2}{4} cup diced onion --- 8 servings

\frac{3}{4} cup diced onion --- \frac{3}{2} × 8 servings = 12 servings
