Answer: x = 4

Step-by-step explanation: To solve this equation, we start by distributing the 4 through the parentheses on the left side.

So we have 4(a) which is 4a and 4(10) which is 40.

So our equation now reads 4a + 40 = 80.

Solving from here, we subtract 40 from both sides of the equation and we have 4a = 40 and dividing both sides by 4, we find that <em>x = 4</em>.

Answer:

Triangle DEF is not a right triangle ; possible lengths are 20 & 15

For right triangle;

the sum of the square of the two adjacent sides must equal the square of the hypotenus.

Therefore, (6^2)+(11^2)≠(13^2).

the possible length are 20 & 15 because

(20^2)+(15^2)=(25^2)
