Answer:
35y2+13y−12
=35y2+28y−15y−12
=7y(5y+4)−3(5y+4)
=(7y−3)(5y+4)
Therefore, the possible length and breadth are 7y-3 units and 5y+4 units
The top part of the shape is 8x6 and the bottom part is 6x6 so the answer is 84
Answer:
43100 cubic feet
Step-by-step explanation:
Floor 1: 3700 * 8 = 29600
Floor 2: 50 * 30 * 9 = 13600
Total = 29600+13600=43100
Answer the answer is 25
Explanation:
You can solve this by finding all of the factors of 28 and seeing which ones add up to 22 when doubled.
The factors of 28 are as follows:
28 x 1 28(2) + 1(2) = 56 + 2 = 58 ≠ 22
14 x 2 14(2) + 2(2) = 28 + 4 = 32 ≠ 22
7 x 4 7(2) + 4(2) = 14 + 8 = 22
The dimensions of the rectangle are 4 x 7.
