Answer:
x = 12
Step-by-step explanation:
The two angles are complementary since they form a 90 degree angle.
35+ 4x+7 = 90
Combine like terms
42 +4x = 90
Subtract 42 from each side
42-42 +4x =90-42
4x = 48
Divide each side by 4
4x/4 = 48/4
x = 12
I know none of these are actually the answer but odysseyware gave me credit for
(4,2)
Answer:
(5x+1)(x+7)
Step-by-step explanation:
4x^2+26x+6+x^2+10x
5x^2+36x+7
(5x+1)(x+7)
Prove
5x*x + 5x*7 + 1*x + 1*7
= 5x^2 + 35x + x + 7
= 5x^2 + 36x + 7
(_ , _) means (X , Y)
(25 , ) means
X = 25 then you need find the value of Y from the equation .

so the first answer is (25,-3)
..............
( , -8) means
Y = -8 then you need to find the value of X from the equation .

so the second answer is ( 0 , -8 )
hope this would help you
