Answer:
5 (x + 1) (4 x^2 - 5 x + 3)
Step-by-step explanation:
Simplify the following:
(4 x^2 - 5 x + 3) (5 x + 5)
Factor 5 out of 5 x + 5:
Answer: 5 (x + 1) (4 x^2 - 5 x + 3)
Answer:
18° and 72°
Step-by-step explanation:
let x be the measure of one angle then the other is 3x + 18
The sum of the 2 complementary angles = 90°, hence
x + 3x + 18 = 90
4x + 18 = 90 ( subtract 18 from both sides )
4x = 72 ( divide both sides by 4 )
x = 18
the 2 angles are 18° and (3 × 18 ) + 18 = 72°
Rectangle perimeter is 53 meters.
L = W + 2.3
To find the options of a perimeter, divide by 4.
= 13.25
So if this was a square, it would be 13.25 for both L and W but it's not.
Since the W has 2.3 meters more then the L, we do this.
13.25 + 2.3 = 15.55
13.25 - 2.3 = 10.95
Two of your sides equal 15.55, and the other two equal 10.95.
Hope this helps!
