Answer: Length ≥ 6 feet
Step-by-step explanation:
The area of a rectangle= length × width
In this case, the width is 4 feet and the area of the stage must be at most 24 square feet.
The inequality that describes the possible lengths (in feet) of the stage would be:
Length × Width ≥ 24
Length × 4 ≥ 24
Length ≥ 24/4
Length ≥ 6
Therefore, the length must be at most 6 feet.
Answer:
Length, l = 11 ft.
Width, w = 9 ft.
Step-by-step explanation:
From the given data, the area of the rectangle = 99 ft².
Area of the rectangle = Length, l X Width, w
Here, Length, l = 7 more than twice the width
⇒ Length, l = 7 + 2w
Therefore, Area, A = 99 = (7 + 2w)w
⇒ 99 = 7w + 2w²
⇒ 2w² + 7w - 99 = 0
Solve the Quadratic equation using the formula: x =
for the quadratic equation ax² + bx + c = 0.
Therefore, w = 


Since,
we get:

This gives two values of 'w', viz., w =
, 

⇒ w =
, -9.
We take the integer values.
If w = -9, then l = 2(-9) + 7
⇒ l = - 18 + 7 = - 11
Therefore, the length, l of the rectangle = - 11 ft.
and the width, w of the rectangle = - 9 ft.
Hence, the answer.
I believe that once Antoine has been walking for 75 minutes his brother will habe caught up, and this would mean his brother had walked for 44 minutes
Answer:
Step-by-step explanation:
look at the pictures. they should help.
when you have a triangle and you are trying to find the exterior angle you need to find the interior angle that is opposite of the exterior angle. they should both add up to 180 because it will be on a straight line. what ever numbers you have left should be for both angles.
