Answer:
(4 * 5)^3 ;
8000
Step-by-step explanation:
Andre's statement :
Multiply 4 by 5 = 4 * 5 = 20
Cube the result = 20³
The equal expression from the option :
A.) (4 * 5)^3
Also, (4 * 5)^3 = 20^3 = 20 * 20 *20 = 8000
Answer:
x= -8 , y = 5
x= 25/4 , y = 1/4
Step-by-step explanation:
substitute first eqn into the second eqn:
(7 - 3y)^2 -y^2 = 39
49 - 42y + 9y^2 - y^2 = 39
8y^2 - 42y +10 =0
4y^2 - 21y + 5 = 0
(4y-1) (y-5) = 0
y= 1/4 , 5
when y=1/4
x = 7- 3/4
=25/4
when y= 5
x = 7- 15
= -8
The answer in an improper fraction is
47/36
As a mixed number, it is 1 11/36
Hope you become an expert at this soon :)
If u separate these into 2 triangles then they will become 90 degree triangles so angle a=angle c.
