Answer:
option 1
Step-by-step explanation:
Sum of 8 and 7 = 8 + 7
14 times sum of 8 and 7 = 14 x (8 + 7)
Divided by 6 = 14 × (8 + 7) ÷ 6
Answer:
see the explanation
Step-by-step explanation:
step 1
The original area of the rectangular clearance section is equal to
----> equation A
we know that
The length is twice the width
----> equation B
substitute equation B in equation A
step 2
During a sale, the section is expanded to an area of
so
To find out the amount of the increase in the length and width of the clearance section, subtract the areas
therefore
The amount of the increased area is 
Answer:
1. x - 5 = 20
2. x + 2y = -6
3. 5x² = 12
Step-by-step explanation:
1. 5 less than x is 20
x - 5 = 20
2. the sum of x and twice y equals -6
x + 2y = -6
3. the product of 5 and x squared results in 12
5x² = 12
Answer:
A) ∠L = 67.5°
B) ∠E = 112.5°
C) ∠K = 112.5°
D) ∠H = 67.5°
Step-by-step explanation:
A) ∠L is alternate interior to ∠F so it is equal to 67.5°
B) ∠E is supplementary to ∠F so ∠E = 180° - 67.5° - 112.5°
C) ∠K is alternate exterior to ∠E so ∠K = 112.5°
D) ∠H is a vertical angle to ∠F so ∠H is 67.5°
