X=22.2
do the math (I just added this so its valid)
7(3x + 2) = 18 - (x + 48)
Distribute on both sides. On the left side, multiply each term in parentheses by 7. On the right side, a negative sign to the left of parentheses is as if a -1 is there, and you must multiply everything inside the parentheses by -1.
7(3x + 2) = 18 -1(x + 48)
21x + 14 = 18 - x - 48
21x + 14 = -x - 30
22x = -44
x = (-44)/22
x = -2
Answer: x = -2
Answer:
True
Step-by-step explanation:
If a quadrilateral (with one set of parallel sides) is an isosceles trapezoid, its legs are congruent.
y = x + 1.8
15.6
because 6×2.60
y = mx+ b
m=slope
-1/2
x > -1
