Given equation is 2x²+x-28 = 0
⇛ 2x²+8x-7x-28 = 0
⇛ 2x(x+4)-7(x+4) = 0
⇛ (x+4)(2x-7) = 0
⇛ x+4 = 0 or 2x-7 = 0
⇛ x = -4 or 2x = 7
⇛x = -4 or x = 7/2.
I believe this relationship would be a function then since all the x-values are different .
Answer: 71 children ate hotdogs at the picnic.
Step-by-step explanation:
Given: About 32% of the 104 children who ate a school picnic ate hamburgers.
The number of children ate hamburger = 32% of (104 children)
= 0.32 x 104
= 33.28 ≈ 33
Thus, the number of children ate hamburger = 33
Number of children ate hotdogs = 104-33 = 71
Hence, 71 children ate hotdogs at the picnic.
