Perimeter means the sides add up to 12.
Rectangles have two pairs of equal sides.
2(one side) + 2(another side) = 12
2 (one side + another side) = 12
(one side + another side) = 6
To draw a rectangle with a perimeter of 12 units, the two adjacent sides must add up to 6.
1 + 5
2 + 4
3 + 3
1 Expand
1.4t-0.4t+1.24=5.8
2 Simplify 1.4t-0.4t+1.241.4t−0.4t+1.24 to t+1.24t+1.24
t+1.24=5.8
3 Subtract 1.241.24 from both sides
t=5.8−1.24
4 Simplify 5.8-1.245.8−1.24 to 4.564.56
t=4.56
for example lets use 3^2 + 4^2, you add the main numbers, 3 and 4 to get 7, then there are still the exponents, the squared signs, they don't change, they stay as a two. If your problem required a single whole number, then you have to square the 7, 7*7 is 49, so that or 7^2 would be your final answer.
