The question is on the picture

B

Step-by-step explanation:

Volume of a triangular pyramid =

where b = area of base and h = height

We are already given that the height is 17in

All we need to do is find the area of the base.

The base is a triangle with a base length of 12 in and a height of 10 in

To find the area of a triangle we multiply the base length by the height then divide by 2

so area = (12 * 10 ) / 2

12 * 10 = 120

120 / 2 = 60

Hence the area of the base is 60in²

Now we plug in the values into the formula for volume of a pyramid

V = 340

Hence the answer is B

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x

step-by-step explanation:

at each of the parallel lines adjacent angles are supplementary. the angles have special names identifying their positions with respect to the parallel lines and transversal. they are corresponding angles, alternate interior angles, or alternate exterior angles. an angles is congruent to its matched angle.
