:) Brainliest pls?

Answer:

The zeros are {2, -3, -4} which need to be plotted on the x-axis.

Step-by-step explanation:

I'll find the zeros, aka x-intercepts, and you could probably graph them.

To find the zeros, let's factor this polynomial:

r(x) = (x - 2)(x^2+7x+12)

r(x) = (x - 2)(x + 3)(x + 4)

The zeros are {2, -3, -4} which need to be plotted on the x-axis.

Find the slope that is PARALLEL and PERPENDICULAR to the equation of the line y = -1/2x+6.
kifflom [539]

Answer:

parallel: -1/2

perpendicular: 2

Step-by-step explanation:

lines that are parallel have the same slope because they never intersect

lines that perpendicular, have the opposite reciprocal slope.

y = mx + b

where m is the slope

y = -1/2x + 6

-1/2 is the slope.

the slope in the equation given: -1/2

the slope parallel to the line given : -1/2

the slope perpendicular : opposite reciprocal, so the opposite of -1/2 is 1/2 and the reciprocal of 1/2 is 2.

A box has a square base with an area of 16 sq.in. Its is 14 inches tall. what is the volume?
babunello [35]

Answer:

224 inches cubed.

Step-by-step explanation:

Because the area of a square is 16 square inches, the side length is 4 inches. This is because a square's formula for area is the side squared.

Since the box is 14 inches tall, we multiply 4 inches by 4 inches by 14 inches. This means the answer is 224 inches cubed.

We also notice we don't need a measurement for the base sides, we only need to multiply the area by the height.
