Answer: Choice A
The area of the rectangle is equal to the number of unit squares that cover the rectangle. The area of the rectangle is 24 square units.
=====================================================
Explanation:
Imagine drawing equally spaced grid lines to subdivide the rectangle. This splits the rectangle into smaller squares. In this case, each little square is 1 square unit. Having 24 of these squares leads to a total area of 24 square units.
We could have 8 rows and 3 columns of these squares to get 8*3 = 24 total. Or we could have 6 rows and 4 columns to get 6*4 = 24. Another configuration is 12 rows and 2 columns which leads to 12*2 = 24.
Answer:
Step-by-step explanation:
2-6=-4
-4÷5x=
-0.9^X
3×(2+6)+4×5 is/= 44,
3×2+3×6+4×5=44
5×4+3×(6+2)=44
(6+2)×3+4×5=44
3×2+(6+4)×5= 56
So your answers are A, B, and C.

Answer:
? = 4
Step-by-step explanation:
You are in the third quadrant. You want the answer to come out to the equivalent of 225o or pi + pi/ 4 = 5/4 * pi
x - pi/2 = 5/4 pi
x = 5/4 pi + pi/2
x = 5/4 pi + 2*pi / 4
x = 7/4 pi
? = 4
