Answer:
x^2+3x-4
Step-by-step explanation:
x * x - x + 4x - 4
x^2 - x + 4x - 4
x^2 + 3x - 4
1/15=144/x
Cross multiply
X=2,160
Gymnasium=2,160 ft2
Answer:
x° = 79°
z° = 101°
Step-by-step explanation:
Answer:
z=96, because we know that any straight line is equivalent to 180 degrees, so we subtract 180-48-36=96.
To find x we first make an equation 6x+96+36=180
6x+132=180
6x=180-132
6x=48
6x/6=48/6
x=8
and also cause why not y=96 as well same principle applies.
