Answer:
x = 12
y = 4
Step-by-step explanation:
x + y = 16
x - y = 8
y + 8 = x
Replace x with y + 8 in the new equation
8 + 2y = 16 ----> we can minus 8 on both sides
2y = 8 -----> divide both sides by 2
y = 4
Now for the x value
x + 4 = 16 ----> minus 4 on both sides
x = 12
Since line c and d are parallel, line a can act as a transversal. Thus, x=124 degrees because of the alternate exterior angle relationship that can be seen.
It’s 9 but are you serious
9 + √2 / 4 - √7
Multiply the numerator and denominator by the conjugate.
Exact form:
(36 + 9√ 7 + 4√2 + √14) / 9
or
about 7.69
