Answer:

2.4 years

Step-by-step explanation:

you have to first convert the trees' heights into inches. three feet is equivalent to 36 inches and four feet is equivalent to 48 inches. Since three A grows at 15 inches a year it'll become a the expression 15x+36 and the expression for tree B will be 10x+48. You set them up to each other and simplify it.

15x+36=10x+48

 -10x        -10x

5x+36=48

   -36        -36

5x=12

/5    /5

x=2.4

So it'll be 2.4 years

John owes a debt of $500 to his landlord. His father has agreed to pay 3/5
Furkat [3]
John’s father will pay $300.

If you divide $500 into 5 equal parts, each part will be comprised of $100. In other words, 1/5 of $500 is $100. This is proven because $100 • 5 = $500.

But since you are trying to find 3/5 of $500, (not 1/5, which is what we just found). This means we must find the total value of 3 of the five equal parts. To do this, multiply
$100 • 3, since $100 is 1/5 of $500.
$100 • 3=$300, so the answer is B. Johns father will pay $300.

X sqaured plus 4x plus 20 equlas 12x minus 5
skelet666 [1.2K]

Answer:

x² + 4x + 20 = 12x - 5

x² + 4x - 12x + 20 + 5 = 0

x² - 8x + 25 = 0

Δ = √b² - 4ac

= √(-8)² - 4×1×25

= √64-100

= √(-36)

x ∉ R
