Which expression is equal to... (in picture)

creativ13 [48]

Answer:

The expression equal to the problem given is the last answer 3(x-2)(x+5)/2x(x-5).

Step-by-step explanation:

In order to solve the problem, you first need to factor your quadratic equations in order to simply the expression. Starting with 3x^2 +12x-15, we can factor that into 3(x+5)(x-1). 4x^2 +4x - 8 would factor to 4(x+2)(x-1). Between these simplified expressions, we can cancel out (x-1) from the numerator and denominator. For the next fraction, we can factor 2x^2 - 8 into 2(x-2)(x+2) and factor x^2 - 5x into x(x-5). When we see the factored fraction expressions side by side, we can then cross-simplify the 2 and 4 as well as the (x+2) from the denominator of the first fraction and the numerator of the other. This leaves us with a final combined expression of 3(x-2)(x+5)/2x(x-5).

I bought 120g of candies for $1.65, how much would 70g cost, and how much could i buy for $3.80

VladimirAG [237]

70 g* ($1.65/ 120 g)= $0.96.

$3.80* (120 g/ $1.65)= 276.364 g.

70 g of candies would cost $0.96
With $3.80, we can buy 276.364 g of candies~

If on a scale drawing 15 feet are represented by 10 inches the. A scale 1/10 inches represents how many feet

Goryan [66]

Answer:

A scale 1/10 inches represents 0.15 feet

Step-by-step explanation:

* Lets explain how to solve the problem

- The scale drawing is a ratio between the actual length and the

drawing length

- The terms of the ratio must have same units, then the scale

drawing must have same units

* Lets solve the problem

- The 15 feet on a scale drawing are represented by 10 inch

∵ 1 foot = 12 inches

∴ 15 feet = 15 × 12 = 180 inches

∵ 15 feet represented by 10 inches

∴ 180 inches represented by 10 inches

∴ The scale drawing is ⇒ 10 : 180

- Simplify it by dividing the two terms by 10

∴ The scale drawing is ⇒ 1 : 18

- That means every 1 inch in drawing represents 18 inches in actual

∵ A scale represents 1/10 inches

∴ 1 : 18

1/10 : ?

∴ The actual = 1/10 × 18 = 1.8

∴ 1/10 inches in scale drawing represents 1.8 inches in actual

∵ 1 inch = 1/12 feet

∴ The actual = 1.8 × 1/12 = 0.15 feet

* A scale 1/10 inches represents 0.15 feet
