Answer:
(2r - 8)(2r + 8).
Step-by-step explanation:
4r2 – 64
This is the difference of 2 squares so we take the square root of 4r2 and 64 and write:
= (2r - 8)(2r + 8).
Answer: 200 hats in total
Steps:
x * .4 = 80
x = 80/.4
x = 200
Check:
200 * .4 = 80
80 = 80 ✅
keeping in mind that the vertex is half-way between the focus point and the directrix, and since the focus point is above the directrix, meaning the parabola is a vertical parabola opening upwards, the parabola will more or less look like the one in the picture below, with a distance from the vertex of "p" being positive since it's opening upwards.
Answer:
B. -2
Step-by-step explanation:
Simply plug 3 into the equation and follow the order of operations.
2(3 - 4) + (3(3)) - (3^2)
2(-1) + (9) - (9)
= -2
Answer:
GH = 9 units
Step-by-step explanation:
Given HI = 4b - 5 and HI 3, then
4b - 5 = 3 ( add 5 to both sides )
4b = 8 ( divide both sides by 4 )
b = 2
Thus
GI = 5b + 2 = 5(2) + 2 = 10 + 2 = 12
GH = GI - HI = 12 - 3 = 9
