Answer:
L=8, W=4
Step-by-step explanation:
2L+2W=p
2(4)+2(8)=p
8+16=24
Answer:
(4p^2-28pq)
Step-by-step explanation:
You have to times 4p by p meaning you get 4p squared as p multiplied by p gets you a squared. for the second half, 4x7= 28, and p multiplied by q is pq so it would be 28pq
Answer:
Since the first equation x is equal to 4y - 9, it is easier to substitute 4y - 9 in for x in the second equation.
x = -1 y = 2
Step-by-step explanation:
Since the first equation x is equal to 4y - 9, it is easier to substitute 4y - 9 in for x in the second equation. That would give you
4y - 9 + 4y = 7
8y - 9 = 7
8y = 16
y = 2
x = 4y - 9 = 4(2) - 9 = 8 - 9 = -1
It is always a good idea to check and see if your results satisfy the two equations
Answer:
a
Step-by-step explanation:
Under a rotation about the origin of 180°
a point (x, y ) → (- x, - y ) , thus
A(- 1, - 1 ) → A'(1, 1 )
The solutions to an algebraic equation equal the highest power in that equation. So, in this case, the answer is 23.
