Answer:
C. 14.
Step-by-step explanation:
We use the identity:-
a^2 + b^2 = (a + b)^2 - 2ab
So 4 = (a + b)^2 - 2(5)
(a + b)^2 = 4 + 2(5)
= 14.
14
(a+b)^2
(a+b)(a+b)
FOIL
a^2 + ab+ab + b^2
Combine like terms
a^2 +2ab + b^2
Rearranging
a^2+b^2 +2ab
We know a^2+b^2 = 4 and ab= 5
4 + 2(5)
4+10
Answer: C) 785.4
The answer is the bottom left
y = -2/3x + 3
y = -2/3x + b
5 = -2/3(-3) + b
5 = 2 + b
3 = b
Corresponding angles are equal so,
m<6= 110° (being the corresponding angle)
.°. m<6= 110°
Hope this helps you!
