Answer:

14 AND 22

Step-by-step explanation:

LET THE LARGER NUMBER BE X AND SMALLER BE Y

X + Y = 36 …….1

2X – Y = 6…… 2

WE SOLVE SIMULTANOUSLY  

ADDING EQATION 2 AND 1

2X + X  + Y + (-Y) = 36 + 6

3X + Y – Y = 42

3X = 42

DIVIDING EACH TERM BY 3

3X/3 = 42/3

X = 14

THEN PUTTING X = 14 IN EQUATION  1

14 + Y = 36

Y = 36 – 14  

Y = 22

Angela makes a pillow in the shape of a wedge to use for watching tv. The pillow is 12 feet three squares of fluffy material
Hunter-Best [27]

Answer:

4 feet.

Step-by-step explanation:

Please consider the complete question.

Angela makes a pillow in the shape of a wedge to use for watching tv. The pillow is filled with 12 cubic feet of fluffy material. The base is 3 ft, the height is 2 ft. What is the length measure?

We know that a wedge is in form of triangular prism, so the volume of wedge will be equal to volume of triangular prism.

\text{Volume of triangular prism}=\frac{1}{2}(\text{length}\times\text{ width}\times \text{Height})

Upon substituting our given values in above formula, we will get:

12\text{ ft}^3=\frac{1}{2}(\text{length}\times3\text{ ft}\times \text{2 ft})

12\text{ ft}^3=\text{length}\times3\text{ ft}^2

\frac{12\text{ ft}^3}{3\text{ ft}^2}=\frac{\text{length}\times3\text{ ft}^2}{3\text{ ft}^2}

4\text{ ft}=\text{length}

Therefore, the length of the pillow is 4 feet.
