After one side of a square was enlarged by 2 inches and the other side was enlarged
by 3 inches, the area of the shape was doubled.
What was the side of the square?

Answers

Answer 1

Answer:

6 inches

Step-by-step explanation:

basically, first write an equation

2x^2 = x^2 + 5x + 6

then simplify this into

x^2 = 5x + 6

then use sum-product pattern and factor

(x - 6)(x + 1) = 0

then split into two equations

x - 6 = 0, x + 1 = 0

so, you have x = 6 and x = -1

because it can't be negative, 6 is your answer

For S if the ratio is 2:7 and you use 20 drops of red paint you multiply 2 by 10 which is 20 so you also multiply 7 by ten to get 70 (So the answer for S is 70 drops) and for L you multiply 2 by 20 to get 40 so you multiply 7 by 20 and you get 140 (The answer for L is 140 drops) For T you multiply 2 by 1.5 to get 3 so you multiply 7 by 1.5 which is 10.5 ( so the answer for T is 10.5 drops)

Lila and Drew want to buy their mom a gift that costs $30. Raquel has $18 saved already, how much does Drew need to save to pay for the gift?

Let d = the amount that Drew has to save to help buy the gift.

Which equation can be used to solve the problem. Equation

How much money does Drew need to save so they could buy the gift?















Answers

A number decreased by 11 is equal to 48

x - 11 = 48

Lila and Drew:

18 + d = 30

To solve, subtract 18 from both sides of the equation. That gives you:

d = 12

Answers

Answer:

roots: 1 and 3

k = 3

Step-by-step explanation:

2 roots: p and p+2

(x-p) (x-p-2) = x² - 4x + k

x² -2px -2x + p² + 2p = x² - 2 (p+1)x + (p² + 2p) = x² -4x + k

-2 (p+1) = -4

p+1 = 2

p = 1   ... root 1

p' = 1+2 = 3   ... root 2

k = p² + 2p = 3

check: (x-1) (x-3) = x² - 4x + 3 = x² - 4x + k
