Answer:56
Step-by-step explanation:do 180-68, then divide by 2(because the x angles are equal to each other.
15 per child 7 go in so 15-7=8 the answer is 8 more children can jump is the bounce house
Hope this helped
Answer:
The distance added to each dimension is 2 yards.
Step-by-step explanation:
The initial dimensions of the rectangular fence is 8 yards by 4 yards.
The initial area of the rectangular fence = area of a rectangle
area of a rectangle = length x width
So that,
The initial area of the fence = 8 x 4
= 32
The initial area of the fence is 32 square yards.
But, with the new dimensions, area = 60 square yards.
(4 + x) x (8 + x) = 60
+ 12x + 28 = 60
+ 12x - 32 = 0
(x + 14) = 0 or (x - 2) = 0
x = -14 or x =2
Thus, x = 2
The distance added to each dimension is 2 yards.
This is indeed a linear equation. y-4x=9 in standard form is y=4x+9.
