Answer:
170 m
Step-by-step explanation:
Area of a rectangle is width times length:
A = WL
Given:
A = 1764
W = L + 13
Substitute:
1764 = (L + 13) L
1764 = L² + 13L
0 = L² + 13L − 1764
0 = (L + 49) (L − 36)
L + 49 = 0, L − 36 = 0
L = -49, L = 36
Since length can't be negative, L = 36 m.
So the width is W = L + 13 = 49 m.
Perimeter of a rectangle is twice the width plus twice the length.
P = 2W + 2L
P = 2(49) + 2(36)
P = 170 m
The perimeter is 170 meters.
Answer:
Step-by-step explanation:
1.The expression given is in division so when changing to multiplication the fraction is reversed.
2.Using algebra identity 
.
3. Taking the common factor 5 out.
4. Finally cancelling the like terms from the numerator and denominator.
C. 6/5 * 4
6/5 = 1.20 where .20 represents the 20% increase in serving.
1.20 * 4 = 4.8 is the total cups of flour needed to increase serving by 20%
4 is the 100% ; the desired increase is 20%; therefore: 100% + 20% = 120% based on 4 cups. So, 120% ÷ 100% = 1.2 * 4 = 4.80 cups
Answer:
Step-by-step explanation:
<u>Corresponding side have same ratio:</u>
- 55/121 = 5/11 (divide by 11)
- 40/88 = 5/11 (divide by 8)
- 30/66 = 5/11 (divide by 6)
The similarity ratio or the scale factor of the larger triangle to the smaller is 5/11
