You need 3a^3 to equal a^3, so you would need at subtract 2a^3.
Since the problem is addition, add - 2a^3:
3a^3 + -2a^3 = 3a^3 - 2a^3 = a^3
Then you have -5b^3 and you need it to equal b^^3, so you would need to add 6b^3:
-5b^3 + 6b^3 = b^3
First box would be -2
Second box would be 6
Factor out the GCF first
3(2x² - x - 10)
3(2x - 5)(x + 2)
The total number of cups for younger kids is 3.66 and for the older kids its 7.5 so if you add those together it is about 11.16 which is less than 12 cups, so your answer is yes she does have enough
Answer:
86 m²
Step-by-step explanation:
It can be convenient to think of the figure as an 8×12 rectangle with a 4×5 triangle cut off the corner.
The rectangle area is the product of its length and width:
(12 m)×(8 m) = 96 m²
The triangle area is half the product of its base and height:
(1/2)(4 m)(5 m) = 10 m²
Then the area of the figure is the difference of these:
96 m² -10 m² = 86 m²
Brandon's rectangle:
Length = 8.75 x 1.5 = 13.125 inches
Width = 6 x 1.5 = 9 inches
If you need the area and perimeter then here:
Area = 13.125 x 9 = 118.123 inches square or sq in.
Perimeter = 2 x (13.125+9) = 44.25 in
