Answer:
25.5
Step-by-step explanation:
30% of 80 is 25.5
think of it as two fractions, and use the butterfly method
30/100 ?/80
from there solve
Two factors that give a product of 1600 can be 80 × 20
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:80 degree angle
Step-by-step explanation:
There are always 180 degrees so you subtract the 2 others and you get the angle (60+40-180)
