The hole for a support needs to be 4 feet deep. It is currently 2 feet 8 inches deep. How much deeper must the hole be? Use pencil and paper. Show two ways to solve this problem. Use the
12 inches
conversion factor
1 foot
The hole needs to be inches deeper.

i would say b) is your answer

sorry if im wrong

step-by-step explanation:

there is no points to select.

step-by-step explanation:

the answer is about 24 dollars

the area of a triangle is determined by the formula: base x height * 1/2

you'll need to assign a base to the triangle. based on the vertices given, the simplest base would be the line segment from (-2,1) to (2,1). the distance between any two numbers is found by just subtracting them. here, you should subtract the x values to find the distance of this side.

2 - (-2) = 4.

so the distance (aka the length of the base) is 4. the height of the triangle is the distance between the base and the highest point on the triangle which is (3,4). we should subtract the y values this time to find the height/distance.

4 - 1 = 3

so the height is 3.

base = 4

height = 3

hope this if needed hmu
