Answer:
7 and a half and then 13 and a half
Step-by-step explanation:
1.
1 x 5 = 5
5 devided by 2 = 2 and a half
5 + 2 and a half = 7 and a half
2.
1 x 9 = 9
9 devided by 1 half = 4 and 1 half
9 + 4 and 1 half = 13 and 1 half
Answer:(x+6) (x+6)
(x+6)^2
Step-by-step explanation:
36+12x+x^2
x^2 +12x +36
What 2 numbers multiply to 36 and add to 12
6*6 = 36
6+6 =12
(x+6) (x+6)
(x+6)^2
Answer:

Step-by-step explanation:

Answer:
12 cm
Step-by-step explanation:
First, divide the perimeter by the sum of ratios.
=> 84 / (3 + 4 + 2 + 5)
=> 84 / 14
=> 6
Shortest side
= 2x
= 2(6)
= 12 cm
H(x) = 1/9000x^2 - 7/15x + 500 = 1/9000(x^2 - 4200x + 4500000) = 1/9000(x^2 - 4200x + 4410000 + 90000) = 1/9000(x - 2100)^2 + 1/9000(90000) = 1/9000(x - 2100)^2 + 10
h(x) = 1/9000(x - 2100)^2 + 10
