There are 104.6 and 9 groups of 5 in 523 and 45
Answer:
A = 188
Step-by-step explanation:
+ replace x = -6 and y= 2 into 3 x squared minus 5 x y + 5 y squared = A
So A= 3x^2 - 5xy + 5y^2
A = 3 *(-6)^2 -5* (-6) *2 +5* 2^2
A = 3* 36 +60 + 5*4
A= 108 +60 +20
or A = 188
Have a good day
Answer:
Area = 1/2 b x h
18 = 1/2 ((x) x 4x)
18 =1/2 4x^2
36 = 4x^2
36/4 = x^2
9 = x ^2
x = 3
Base = 3 m
Height = 4 x base = 4 x 3 = 12 m
Step-by-step explanation:
It would be 6x12 which equals 72 inches
