Answer:
The answer is 3.9
Step-by-step explanation:
Surface area of the prism is 2xy+2xz+2yz
I think, we can cut hole on the face of the prisma 40x30, and size of the whole will be 5X5X5
hole increases surface area. If side of the cube is "a", then a^2 is the area of the one face of the cube.
when we are doing the hole, we remove 2 faces and add 4 more faces, so
2xy+2xz+2yz-2a^2+4a^2= 2xy+2xz+2yz+2a^2
So, 2*5*40+2*5*30+2*40*30+2*5^2=3150 cm^2
i hope it helps, it is what i can come up with now
Answer:
x = 4
Step-by-step explanation:
Given
= 
( cross- multiply )
4x - 7 = x + 5 ( subtract x from both sides )
3x - 7 = 5 ( add 7 to both sides )
3x = 12 ( divide both sides by 3 )
x = 4
The transformation you'd need to use would be a dilation.
A dilation is a type of transformation that changes the size. <span />
