Simplify: 7p - 4 + 12p
To simplify this expression, simply combine like terms. The expression has two variable terms and one constant term. The variable terms are 7p and 12p, and the constant term is -4. Begin simplifying by combining variable terms (add them together).
7p + 12p
19p
This term (19p) replaces the first p-term in the original expression.
As there is only one constant term (-4), that is all there is to be done to simplify this expression.
Answer:
19p - 4
Answer: 6√7
Step-by-step explanation:
Geometric Mean: Multiply the 2 numbers and take the square root.
6 · 42 = 252
Now take the square root:
√252
Simplify the radical (if needed):
6√7
Your geometric mean is 6√7.

Choice A because it is statistical and the other doesn’t make sense
The answer: [B]: h = 2A / (b1 + b2) .
__________________________________________________________
Explanation:
Given: A = (½) * (b1 + b2) * h ;
________________________________
→Multiply EACH side of the equation by "2", to get rid of the fraction, "<span>½";
</span>____________________________________________________________
→ 2*A = 2 * (½) * (b1 + b2) * h ;
→ 2* A = 1 * (b1 + b2) * h ;
→ 2A = (b1 + b2) * h ;
____________________________
→ Now, divide EACH side of the equation by: "(b1 + b2)" ; to isolate "h" on one side of the equation;
__________________________________________________________
→ 2A / (b1 + b2) = [(b1 + b2) * h] / (b1 + b2) ;
→ 2A / (b1 + b2) = h ; ↔ h = 2A / (b1 + b2) ; which corresponds to:
"Answer choice: [B]" .

Quadrant 2 because it goes to the left because the X is negative then up because the Y is positive.
