Answer: C {3, 4}
Step-by-step explanation:
<em>Solve the inequality:</em>
7x + 6 > 20
7x > 20 - 6
7x > 14
x > 2
Only 3 and 4 are greater than 2.
Perpendicular lines form 90 degree angles.
Letter C.
The unit for area is unit^2. You area for a rectangle is one of the easiest formula in math. A = LW
There’s a few ways to do this. But you essentially want to find the area for each rectangle and add them together.
We can do the two rectangles on the left, bedroom 1 and 3, by doing 3.5 x (4.25+3.75) = 31.5 in^2
Now do bedroom 2, we have to do 7.5 - 3.5 to get the width of the room since it wasn’t given directly. The width is 4 and we have the length of 3.5. Do 4 x 3.5 to get 14 in^2
31.5 + 14 = 45.5 in^2
We’re not done yet because they want it in ft^2 and we’re given 1 inch = 4 feet
Just do 45.5 x 4 to get 182 ft^2
Step-by-step explanation:
there are 45 odd numbers
