Answer:
180
Step-by-step explanation:
Area of troiangle=180
A+B+C=180
22+90+B=90
112+B=180
B=180-112
B=68
perimeter=A+B+C
22+90+68=180
Answer:
24=24
Step-by-step explanation:
4(4+3) - 4 = -(6-1) + 29
4 * 7 -4 = -5 + 29
24 = 24
Answer:
y = 3/2 x + 7
Step-by-step explanation:
Line intercept form =
Y = mx + b
m is the slope (rise over run) and b is the y intercept.
So what you want to first is get y by itself.
9x-6y = -42
-6y = -42 - 9x
y = 9/6 x + 7
y = 3/2 x + 7
The correct answer is A, x-4
