Use the zero product property to find the solitions to the equation(x+2)(x+3)=12.
kykrilka [37]

Answer:

(x + 2) (x + 3) = x² + 3x + 2x + 6 = 12  (multiply the binomials)

(x + 2) (x + 3) = x² + 5x + 6 = 12

(x + 2) (x + 3) = x² + 5x + 6-12 = 0  (add the like term and bring the positive 12 to the other side which makes it negative)

x² + 5x + 6 = 0

Using the snowflake method -  (finding the factors of 6 that adds/subtracts to give you 5).  

This method will give you the factors (x + 6)(x - 1)

ZERO PROPERTY RULE:

(x + 6) = 0

x = -6

(x - 1) = 0

x = 1

The two solutions to the equation are -6 and 1.

She purchased 40% of the copies in the store. She has 80 copies of the cd. How many cd were on sale
mafiozo [28]
To find the number of CD on sale, we can set an equation.

Let y be the number if CD.

As she bought 40%, the amount she bought= 40%y

The equation:

40%y = 80

0.4y = 80

y = 80÷0.4

y=320

Therefore there were originally 320 CDs.

Please help me!! This is math 7th grade
Musya8 [376]

Answer:

14) false

15) false

Step-by-step explanation:

14) 120% of a positive whole number is always greater than the number. If the number is 1, 120% of it would give us 1.2 which is greater than 1. However if the number is a negative whole number, 120% of it would give us a smaller number. Let's try -1. 120% of -1 would give us -1.2, which is smaller than -1. Hence the statement is false.

15) 0.5% of a number is 0.5/100 of the number so we should multiply the number by 5/1000. 5/100 is only 5% of the number. Hence the statement is also false.

What are the solutions to the quadratic equation (5y + 6)2 = 24?
lana [24]
To solve for y, apply the distributive property:
10y + 12 = 24
Then, subtract 12 from both sides and you will get:
10y = 12 \\
Then solve for y, by dividing both sides by 10.

Your final answer will be y=1.2
