Answer:
2z - 3w = 8
Step-by-step explanation:
Where you see z you place 10 there and where you see w you place 4 there because that's the value according to the question.
So we have 2(10) - 3(4) = 20 - 12 = 8

Answer:
The side lengths of the image after the dilation = 13.5 cm and 20.25cm
Step-by-step explanation:
A rectangle has side lengths 6 cm and 9 cm. What would the side lengths of the image be after a dilation of 2.25? Explain your reasoning.
Dilation can also be referred to as scale factor
6cm × 2.25 = 13.5 cm
9 cm × 2.25 = 20.25 cm
The side lengths of the image after the dilation = 13.5 cm and 20.25cm
We know that
L=8 ft
W=2 ft
H=3 ft
[<span>surface area of the doll house]=2*[W*H]+2*[L*H]+2*[W*L]
</span>[surface area of the doll house]=2*[2*3]+2*[8*3]+2*[2*8]
[surface area of the doll house]=2*[6]+2*[24]+2*[16]
[surface area of the doll house]=12+48+32--------> 92 ft²
the answer is 92 ft²
