Answer : acute
Right triangle : a^2+b^2=c^2
Acute triangle : a^2+b^2 > c^2
Obtuse triangle:a^2+b^2 < c^2
6^2+7^2 > 9^2
Answer:
Step-by-step explanation:
Use FOIL method
F -> First
O Outside
I inside
L Last
(a - b)(a + 2b)= a*a + a *2b + (-b)*a + (-b)*2b
= a² + <u>2ab - ab</u> - 2b²
Combine like terms
= a² + ab - 2b²
The answer is. A! All you do is times the numbers in A by every time table too find the correct answer.
Blue: 5/20, 0.25%, 0.25
Red : 8/20 0.4%, 0.4
Green: 7/20, 0.35%, 0.35
