Yes because a rational number can be whole numbers, integers, and decimals
315 inches
180+135=315
180*7.5=135 which is 75% of 180
For a right triangle, the Pythagorean theorem can be used to calculate the sides of the triangle. This theorem is expressed as: c^2 = a^2 + b^2. From th problem, we are given c which is the hypotenuse and the other leg which we will assign as the leg a. Calculation is as follows:
<span>c^2 = a^2 + b^2
(155cm)^2 = (124cm)^2 + b^2
b= 93 cm</span>
Answer:
- perfect square: 2, 5
- difference of squares: 1, 6
Step-by-step explanation:
If the two factors are identical, their product will be a perfect square.
If one of the factors is the difference of terms that are summed in the other factor, the product will be the difference of squares.
(a +b)(a -b) = a² -b² . . . . . matches the 1st and 6th choices
(a +b)(a +b) = (a +b)² . . . . matches the 2nd and 5th choices
