Answer:
−19282+104−96
Step-by-step explanation:
hopefully this helps, I'm not sure I'd it is correct though
Every point is translated according to the rule ( x, y ) → ( x + 2, y - 6 )
L ( -1, 2 ) → L´ ( -1 + 2, 2 - 6 ) = ( 1, -4 )
Given the ratio, you know that:
length = 6x
width = 2x
height = 7x
Because the sum of the length and the width is 24 cm, you can write the equation:
6x + 2x = 24
Solve:
8x = 24
x = 3
Plug the 3 back into the expressions written earlier for length, width, and height.
length = 18 cm
width = 6 cm
height = 21 cm
Use the formula SA = 2B + Ph to solve for the surface area.
Surface Area = 2(area of the base) + (perimeter of the base)(height)
I'm going to plug in l, w, and h as variables for length, width, and height to show the exact way to solve for the B and P.
SA = 2lw + 2(l + w)h
SA = 2(18)(6) + 2(18 + 6)(21)
SA = 216 + 2(24)(21)
SA = 216 + 1008
SA = 1224
The surface area is 1,224 cm^2.
Answer:
x = 24
Step-by-step explanation:
distribute the 3
6x - 15 = 4x + 33
Combine like terms by regrouping, remember if the number crosses the equal sign the sign changes.
6x - 4x = 15+ 33
2x = 48
divide both sides by the coefficient 2
x = 24
