Answer:
2x-30
Step-by-step explanation:
5(x-3) = 5x-15
-3(x+5) -3x-15
(5x-15) + (-3x-15) = 2x-30
Answer:
so first you could combine common factors which are x2 and 6x. Subtract them and you get 4x. So your final answer would be 4x - 72 because you cant simplify anymore. 4x and 72 arent like terms so your final answer is 4x - 72.
Step-by-step explanation:
2x - 6x- 72
2x - 6x = 4x
4x - 72
Well...
DB is a median... It means DB divides AC in 2 equal parts. AC = 26. AB = 26 ÷ 2 = 13.

Thee diagonal of the rectangle is 13.86 cm long.
<h3>What is the length of the diagonal of rectangle?</h3>
We are given that;
Width of a rectangle is 9 less than twice its length. Thus, if length is L, then;
W = 2L - 9
Area formula for a rectangle is;
A = Length * Width
We are given area of rectangle = 96 cm²
Thus;
L(2L - 9) = 96
2L² - 9L = 96
2L² - 9L - 96 = 0
Using online quadratic equation calculator gives;
L = 9.53 cm
Thus;
W = 2(9.53) - 9
W = 19.06 - 9
W = 10.06 cm
The diagonal of the triangle will be gotten from Pythagoras theorem;
D = √(9.53² + 10.06²)
D = √192.0245
D = 13.86 cm
Thus, we conclude that the diagonal of the rectangle is 13.86 cm long.
