The heights of a maple tree and a cherry tree have a ratio of 5:2. If the maple tree grew 20 cm and 20 cm was cut off the top of

elena-14-01-66 [18.8K]

Let x be the heights of a maple tree and y be the height of the cherry tree.
We know:
 $\frac{x}{y} = \frac{5}{2}$
The new ratio is obtained like this:
 $\frac{x+20}{y-20} = \frac{3}{1}$ .
From the above equation we get $x= (y-20)\frac{3}{1} -20$ .
then $\frac{ (y-20)\frac{3}{1} -20}{y} = \frac{5}{2}$
Solving the above equation for y we get: $y=160$
So $x=400$
So the first tree is (400-160=240) more taller than cherry tree.

Multiply and simplify. (2x - 1)(6x - 7)

Kryger [21]

Answer:

D) 12x² - 20x + 7

Step-by-step explanation:

Use FOIL when multiplying 2 binomials...

FOIL is Firsts, Outsides, Insides, Lasts. It's the order in which you multiply the numbers in the binomials...

(2x - 1)(6x - 7)

Firsts: (2x)(6x) = 12x²

Outsides: (2x)(-7) = -14x

Insides: (-1)(6x) = -6x

Lasts: (-1)(-7) = 7

Now add them up...

12x² - 14x - 6x + 7

12x² - 20x + 7
