Step-by-step explanation:
Answer:
Step-by-step explanation:
3x-6y=48
Turn the equation into slope intercept form (y=mx+b)
x-2y=16 (Subtract x)
-2y=16-x (Divide by -1/2)
y=1/2x-8
The y-intercept is b, so -8 is the y-intercept.
The slope is m, so the slope is 1/2.
Answer:
V=6
Step-by-step explanation:
H=6
B=3
V=?
V=6*3/3
V=6
The surface area is 870 cm².
Since the base is a regular quadrilateral, each side is the same; dividing the perimeter by 4 will give us the side length:
60/4 = 15
To find the area, we square the side length:
15² = 225
There are two bases, so the area of these is 2(225) = 450
There are 4 lateral faces, so the lateral area is 4(105) = 420
Together, this gives us a total surface area of 870.
Answer:
465 in²
Step-by-step explanation:
square area: A = lw
triangle area: A = 
lw (or base x height)
= (15)(15) = 225
= (8)(15) = 60
There is one square and 4 triangles so...
225 + 4(60) = 465 in²
