Answer:
y^2 + 16y + 64 = 0
(y + 8)(y+8) = 0
y + 8 = 0
y = -8
y + 8 = 0
y = -8
Step-by-step explanation:
Answer:
Step-by-step explanation:
x = small barrettes
y = large barrettes
13x + 11y = 142.......multiply by -1
13x + 12y = 149
-----------------------
-13x - 11y = -142 (result of multiplying by -1)
13x + 12y = 149
------------------------add
y = 7..........large barrettes used 7 yards
13x + 11y = 142
13x + 11(7) = 142
13x + 77 = 142
13x = 142 - 77
13x = 65
x = 65/13
x = 5........small barrettes used 5 yards
Answer:A quadrilateral always has a sum of 360o in total.
Answer: 66s + 180
How:
17 s ^ { 1 } 2 + 32 s + 180
Calculate s to the power of 1 and get s.
17s\times 2+32s+180
Multiply 17 and 2 to get 34.
34s+32s+180
Combine 34s and 32s to get 66s.
Final answer should be 66s + 180
Answer:
Step-by-step explanation:
The three salespeople for a local advertising firm are sara, Kenny and Leila.
Sara sold total ads = $3350
Kenny sold total ads = $1368
Leila sold total ads = $456
First we calculate total sale of all three = 3350 + 1368 + 456 = $5174
We need to find fraction of total sale with each person sell.
