Step-by-step explanation:
it's done by pythagoreans theorem
√25-9=4
6•(4a-3b)
Steps:
Rewrite -18 as 3• 6
Rewrite 24 as 4 • 6
= 4 • 6a + 3• 6b
= 6(4a-3b)
Answer:
My guess is 105
Step-by-step explanation:
7 x 15
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]" .
