Answer:
Perimeter: 18.5
Area: 15
Step-by-step explanation:
P = a + b + c
P = 5 + 6 + 7.5
P= 18.5
A = 1/2bh
A = 1/2*7.5*4
A= 15
1. find the LCD of 3 and 4 (12). so now your fractions are 5 4/12 and 3 9/12 perimeter is 2l + 2w so 2 (5 4/12) + 2( 3 9/12) = 10 4/12 + 7 6/12 = 17 10/12 or 17 5/6. this is reasonable because that the average perimeter of a sandbox.
2. LCD again is 12, so the fractions are 5 10/12 and 2 1/12. turn those into mixed fractions and get 70/12 and 25/12. 45/12 or 3 3/4. So she babysits 3 3/4 hours during the week.
3. The LCD for this is 8. now the fractions are 2/8 and 1 7/8 or 15/8. add 15/8 and 2/8 to get 17/8 or 2 1/8. He is using a total of 2 1/8 cups of flour.
4. 0.2
5. 0.054
6. 0.024
Answer:
(ab-bc)²
Step-by-step explanation:
- ab(ab-bc)+bc(bc-ab) = ⇒ distribution
- (ab)² - ab*bc + (bc)² - ab*bc = ⇒ regrouping
- (ab)² - 2ab*bc + (bc)² = ⇒ applying (x-y)² = x² -2xy +y² formula
- (ab-bc)² ⇒ final result
