Answer: exact form: 7/5
Decimal form: 1.4
Mixed form: 1 2/5
Step-by-step explanation:
-3 =-2x - 7
Add 7 to both sides
4=-2x
Divide by -2
-2 = x
surface area = 4 x pi x r^2
diameter = 1 so radius = 1/2 = 0.5
4 x 3.14 x 0.5^2 = 3.14 meters^2
Y=24 Y-12=12 Y=12+12 Y=24
(X-12) = 12
X = 12+12
X=24
Answer:
Step-by-step explanation:
width=√(130²-120²)=√[10²(13²-12²)]=10√(13+12)(13-12)=10√(1×25)=10×5=50 m
perimeter=2(120+50)=2×170=340 m
area=120×50=6000 m²
