Answer:
-4, 2 i don't really know what to do
Step-by-step explanation:
The answer is -110.
This is because -55-55=-110.
You have to put -55-55 because the question is asking for you to multiply -55 twice, which is technically-55-55.
806 u just add the six in the end
The expression that can be used to find the area of the tiled floor is 4w² + 200w
<h3>Area of rectangle</h3>
Length = 70 Meters
Width = 30 meters
Area = length × width
= 70 × 30
= 2100
- New rectangle(including tiled floor):
Length = 70 + 2w meters
Width = 30 + 2w meters
Area = length × width
= (70+2w) (30+2w)
= 2100 + 140w + 60w + 4w²
= 4w² + 200w + 2100
Area of the tiled floor = Area of new rectangle - area of old rectangle
= (4w² + 200w + 2100) - 2100
= 4w² + 200w + 2100 - 2100
= 4w² + 200w

For the top one it would be about 44 because if you multiply each amount of hours by 11 you'll get the miles. so 44 miles per hour
