How many right triangles have a hypotenuse that measures 2x+5 meters and legs that measure 22xminus−33 meters and x+8 meters? w
hat are the dimensions of the triangle(s)?
1 answer:
<span>
Δ</span>hello :
by theorem pytagore :
(2x+5)² = (22x-33)² + (x+8)²
4x² +20x +25 = 484x²+1452x + 1089 +x²+16x+64
put this expression in the form ax² +bx+c=0
calculate <span>Δ = b²-4ac ....cpntibue</span>

Answer:
y = -3x + 21
Step-by-step explanation:
(5,6)
y = mx + b
6 = -3 × 5 + b
solving for b
b = 6 - (-3)(5)
b = 21
Therefore,
y = -3x + 21
Answer:
Your answer is A:5
By substitution
f(6) = 1.8×2^(6)
= 1.8×64
= 115.2
I think the answer is A sorry if I’m wrong
