Step-by-step explanation:
W = (2L -57)
P = 2×(L+W)
198 = 2× (L + 2L -57)
198 = 2× (3L - 57)
3L-57 = 198/2
3L-57 = 99
3L = 99+57
3L = 156
L = 156/3 = 52
W = 2(52) -57 = 104-57 = 47
so, the length = 52 ft
and the width = 47 ft
Answer:
35 two pointers, 18 one pointers
Step-by-step explanation:
equations:
x + y = 53
x + 2y = 88
solving them:
y = 35
x = 18
1 + 3 = Δ + 3
By comparing
Δ = 1.
Option A.
Answer:
If Nina is N years old and Maryna is M years old the sum of their ages would be N+M
In 6 year from now they you would go the sum of their ages now times 6
You equation would be
6(N+M)
Step-by-step explanation:
The triangle height is calculated by Pythagorean Theorem
height^2 = 15^2 - 9^^2
height^2 = 225 - 81
height^2 = 144
height = 12
We can calculate the value of Angle a
cosine (a) = adj / hyp = 9/15 = .6
arc cosine (a) = 53.13 degrees
angle b = 180 -90 -53.13
angle b = 36.87 degrees
tangent b = height / x
tangent 36.87 = 12 / x
x = 12 / .75
x = 16
Yes, it's just that "simple" LOL
