Answer:

Step-by-step explanation:
Since both are perfect squares use the difference of squares formula
with a =
and b = 3
=
Answer:
D. 1/3
Step-by-step explanation:
D. Perpendicular to each other should be opposite of the slope equation. If it is same slope then,it's parallel to each other, so B is wrong. A and C is wrong, since that is not the given equation is like.
Answer:
=11/4 cm
Step-by-step explanation:
We are finding the perimeter
P = 2(l+w)
l = 3/4 cm
w = 5/8 cm
The common denominator is 8
l = 3/4 *2/2 = 6/8
P = 2(6/8+5/8)
=2(11/8)
=22/8
=11/4 cm (2 1/4 cm)
It says an integer or a fraction, not a mixed number
Answer:
16
Step-by-step explanation:
use the formula (b/2)^2 to find what number to add to each side of the equation
