Answer:
16 - 2r
Step-by-step explanation:
2 times by 4 - 2r = -2 times by r + 5
6 + 4r = -2r - 10
Change the number to its partner.
6 + 10 = -2r - 4r
16 = 2r
So, the answer is 16 - 2r
Answer:
16
Step-by-step explanation:
Area = perpendicular height * base
= DP * CB
= √[(2 - -1.2)^2 + (-5 - (-3.4)^ ] * √[(2 - 0)^2 + (3- -1)^2)]
= √(12.8.) * √(20)
= 16

The amount of paint required to paint the whole cupboard is:

The amount of paint required to paint all but the bottom surface is:
https://tex.z-dn.net/?f=2.5%5E2+%2B+4%282.5%5Ctimes3.5%29%0A%5C%5C%3D+41.25+ft%5E2
So the difference in paint required is 6.25 square feet worth of paint.
