Answer:

x = -15 or 15

Step-by-step explanation:

We can simplify |x| - 3 = 15 to |x| = 15 because we can add 3 on both sides due to -3 being outside of the absolute value bars. Next, we can say that x is either 15 or -15 because of the absolute value (|15| is equal to 15 and |-15| is also equal to 15).

X = -15 or 15
The absolute value of either of those is 15 subtract 3 and it = 12

The dimensions of a rectangular prism are shown below: Length 2 1/4 ft | width 1 ft | height 1 1/4 ft.

zysi [14]

Answer:

See below

Step-by-step explanation:

Dimensions given:

l = 2 1/4 ft, w = 1 ft, h = 1 1/4 ft

A small cube has side of 1/4 ft

Find the number of small cubes can fit in each dimension of the prism.

Length

2 1/4 : 1/4 = 9/4 * 4 = 9

Width

1 : 1/4 = 1 *4 = 4

Height

1 1/4 : 1/4 = 5/4 * 4 = 5

Part A

Number of small cubes would be:

9*4*5 = 180

Part B

Each small cube has volume:

V = (1/4)³ = 1/64 ft³

The volume of the prism in terms of small cubes is 180 as we found above.

The volume in terms of unit cube:

V = 180*1/64 = 180/64 = 2 52/64 = 2 13/16 ft³ or 2.8125 ft³

Solve the system of equations. y=3x y=x^2-10

puteri [66]

Answer:

y=3x.........1

y=x^2-10.......2

substituting value of eq 1 to 2

3x=x^2-10

x^2-10-3x=0

x^2-3x-10=0

x^2-5x+2x-10=0

X(x-5)+2(x-5)=0

(x-5)(X+2)=0

then

X=5 or X=-2

again

y=??

when X=5

y=3×5=15

when X=-2

y=-6
