If the area and width of the rectangle are 45x² − 42x − 48 and (5x − 8) then the length of the rectangle will be (3x + 2).
<h3>What is a rectangle?</h3>
It is a polygon that has four sides. The sum of the internal angle is 360 degrees. In a rectangle, opposite sides are parallel and equal and each angle is 90 degrees. And its diagonals are also equal and intersect at the mid-point.
A rectangle has an area of 45x² − 42x − 48 and a width of 5x − 8.
Then the length of the rectangle will be
area = length × width
Then we have
Area = 45x² − 42x − 48
Then the factor of the polynomial will be
Area = (5x − 8)(3x + 2)
Then the length of the rectangle will be (3x + 2).

Answer:
24
Step-by-step explanation:
Answer:
perimeter of triangle=sum of all sides
perimeter of triangle = 3/10ft + 3/10ft + 1/10ft
perimeter of triangle =7/10ft
GIVEN:
5sinΦ = 3
so, sinΦ = 3/5
let p = 3 and h = 5 as sinΦ = p/h.
ANSWER:
So, by pythagorean theorem,
- b² = (5)² - (3)²
- b² = 25 - 6
- b = √16 = 4.
So, cosΦ = b/h = 4/5.
Now, 2cosΦ + 3sinΦ/3sinΦ + 4cosΦ
- 2 × 4/5 + 3 × 3/5 ÷ 3 × 3/5 + 4 × 4/5
- 8/5 + 9/5 ÷ 9/5 + 16/5
- 17/5 ÷ 25/5
- 17/5 × 5
- 17.
