Answer: -3
Step-by-step explanation:
y = mx + b (slope intercept formula)
9x - 3y = -54
-3y = 9x - 54
Divide all by -3
y = -3x + 18
Slope = -3
Hope this helps!
Answer:
About 23.9 in
Step-by-step explanation:
We are given ;
a circle whose radius is 3.8 inches
we are required to determine the circumference
The circumference is given by the formula;
=2πr
Therefore;
Circumference = 2×3.14×3.8 in
=23.864 in
= 23.9 in
Therefore, the circumference of the figure is about 23.9 in
<span>Simplifying
4x2 + 8xy + 4y2
Reorder the terms:
8xy + 4x2 + 4y2
Factor out the Greatest Common Factor (GCF), '4'.
4(2xy + x2 + y2)
Factor a trinomial.
4((x + y)(x + y))
Final result:
4(x + y)(x + y)</span>
I think it is because they are both different differences
