Answer:
x = 13
Step-by-step explanation:
y=50
50 = 5x - 15
50 + 15 = 5x
65 = 5x
65/5 = 5x/5
13 = x
The answer is 16. 1^2 is 1, 2^2 is 4, 3^2 is 9, and 4^2 would be 16.
Answer:
(2x*+6)(x-2)
2x(x-2)+6(x-2)
2xx+2x(-2)+6x +6(-2)
we know ;
(-). (-) = +
(-). (+) = -
(+). (-) = -
(+). (+) = +
2xx-2x(2)+6x -6(2)
2x^2 - 4x + 6x -12
2x^2 - 2x -12
Step-by-step explanation:
Answer:
87.4°
Step-by-step explanation:
(3x + 8) + (3x + 18) + (7x + 9) = 180
3x + 8 + 3x + 18 + 7x + 9 = 180
add the common numbers
13x + 35 = 180
subtract 35
13x = 145
divide 13
x = 11.2
then plug it back in to m<3
7(11.2) + 9
78.4 + 9
= 87.4°
