Answer:
(a) 6² +3² +1² +1² = 47
(b) 5² +4² +2² +1² +1² = 47
(c) 3³ +4² +2² = 47
Step-by-step explanation:
It can work reasonably well to start with the largest square less than the target number, repeating that approach for the remaining differences. When more squares than necessary are asked for, then the first square chosen may need to be the square of a number 1 less than the largest possible.
The approach where a cube is required can work the same way.
(a) floor(√47) = 6; floor(√(47 -6^2)) = 3; floor(√(47 -45)) = 1; floor(√(47-46)) = 1
__
(b) floor(√47 -1) = 5; floor(√(47-25)) = 4; ...
__
(c) floor(∛47) = 3; floor(√(47 -27)) = 4; floor(√(47 -43)) = 2
.94 times 2.6 would be 2.4
all you have to do is see whether both variables of each point meet both contraints:
for a) 1<3 and 2>1 is true so a is a solution to the system

Answer:
P = 169.6 meters
Step-by-step explanation:
A rectangle is a four sided shape with 4 perpendicular angles. It has two pairs of parallel sides which are equal in distance: width and length. Its area, the amount of space inside it, can be found using the formula A = l*w. If the area is 600.6 m² and the length is 7.8m, you can solve for the width by dividing the area by the length. Division is the inverse operation of multiplication and it will isolate the width.
600.6 / 7.8 = 77 inches.
On contrast, the perimeter is the distance around the shape. It si found by adding all sides together in the formula P = 2l + 2w. Substitute l = 7.8 and w =77.
P = 2(7.8) + 2(77)
P = 15.6 + 154
P = 169.6 meters
