Answer:
The expression 5(4x - 7) + 3(3x + 3) can be simplified to 29x - 26
Step-by-step explanation:
The first step in solving this is to apply coefficients to the contents of the brackets:
5(4x - 7) + 3(3x + 3)
= 5 × 4x - 5 × 7 + 3 × 3x + 3 × 3
= 20x - 35 + 9x + 9
Now you can group like terms:
20x - 35 + 9x + 9
= 20x + 9x - 35 + 9
= (20 + 9)x - 26
= 29x - 26
And that is the final answer.

Sounds as tho' you have an isosceles triangle (a triangle with 2 equal sides). If this triangle is also a right triangle (with one 90-degree angle), then the side lengths MUST satisfy the Pythagorean Theorem.
Let's see whether they do.
8^2 + 8^2 = 11^2 ???
64 + 64 = 121? NO. This is not a right triangle.
If you really do have 2 sides that are both of length 8, and you really do have a right triangle, then:
8^2 + 8^2 = d^2, where d=hypotenuse. Then 64+64 = d^2, and
d = sqrt(128) = sqrt(8*16) = 4sqrt(8) = 4*2*sqrt(2) = 8sqrt(2) = 11.3.
11 is close to 11.3, but still, this triangle cannot really have 2 sides of length 8 and one side of length 11.

Step-by-step explanation:
Just trust me bro
She can make 12 different combinations.
If she used three different colors for the keychain, there's still 4 other colors left.
4 x 3 = 12
