Answer:
The answer is B
Step-by-step explanation:
Answer:
x = 70; the labeled angles are 110º and 70º.
Step-by-step explanation:
The full degrees will add up to 180º. There are 2x and +40.
Equation: 
Solve: 
Since x=70, 70+40 will equal to 110.
Therefore, "x = 70; the labeled angles are 110º and 70º." is correct.
Solution:
100<em>x</em>^2-58<em>x</em>-16
Answer:
16
Step-by-step explanation:
Evaluate the function. f(x) = 4x2 + 4x - 4 Find f(3)
f(3) = 4 x 2 + 4(3) - 4
After this step conduct PEMDAS
f(3) = 4 x 2 + 12 - 4
f(3) = 8 + 12 - 4
f(3) = 20 - 4
f(3) = 16
Answer:
36 cm
Step-by-step explanation:
Let x represent the multiplier of the ratio units. Then the perimeter is the sum of the side lengths:
77 = 25 + 4x +9x
52 = 13x . . . . . . . . subtract 25
x = 4 . . . . . . . . . divide by 13
4x = 4(4) = 16 . . . . find the other side lengths
9x = 9(4) = 36
The side lengths are 25 cm, 16 cm, 36 cm. The longest side is 36 cm.
