Answer:
ab²
Step-by-step explanation:
Step 1: Write out the expression
Step 2: Cross out like terms
The <em>a</em>'s cancel out, leaving <em>a </em>in the numerator
The <em>b</em>'s cancel out, leaving b² in the numerator
Step 3: Finalize
And you have your final answer!
You can cross multiply to get 4 * 21 = 7x
84 = 7x; divide both sides by 7
12 = x so the number 12 will go in the blank (12 girls)
39 inches total
11-3=9
6+3+3+9+3+4+11=39
V = (1/3)(24)(12) = 96 cubic units.
The volume would be 96 cubic units.
4x + 12
(x+3)×4
(x×4) + (3×4)
44 sq. ft
5(2^2) = 20
4(3x2) = 24
20+24 = 44
