Solve the equation for x by finding a, b, and c of the quadratic then applying the quadratic formula.
x = 7,3
Answer:7 Feet below ground
Step-by-step explanation:
1st: Since it says our hole is dug down 8ft to begin with we can start with x=-8
2nd: After a short break, it says we dug down another 3 feet which is -8-3=-11 which shows we are 11 feet below ground where the negative number showcases we are below ground level.
3rd:
After this we are shown a tractor accidentally fills in the hole with 4ft of dirt which signifies that we lose some of our holes height below ground so we would add four: -11+4=-7 this shows that we are finally seven feet below ground.
Answer:
x (8, 0) y (0, -4) I think
Answer:
w = 6
Step-by-step explanation:
Midsegment theorem states that "a segment connecting midpoints of the two sides of a triangle is parallel and half in measure of the third side."
By this theorem,
ST = 2(PR)
w + 6 = 2w
(w + 6) - w = 2w - w
w = 6
