X^2 + 4x + 4 = 0please help!! I missed class! show steps!​

Mathematics
1 answer:
Stels [109]3 years ago
7 0

Answer:

x= -2

Step-by-step explanation:

Step 1. In order to find the zeros of the function, we must factor it.

Step 2. To factor this, we have to find  two numbers that multiply to 4 and add to 4 which is 2 ( 2*2=4 and 2+2=4)

step 3. 0=(x+2)(x+2)

Step 4 make (x+2) equal to zero and solve which gives us -2, so -2 =x.

Help is this correct??(
eimsori [14]
The right answer to 1b is 1 5/8 and the right answer to number 1e is 1 3/7. The way I solved this was by starting out adding two fractions at a time...

1b).     5/8 + 5/8 + 3/8
           5/8 + 5/8 = 10/8 or 1 1/4
           10/8 + 3/8 = 13/8 or 1 5/8.


1e).     5/7 + 1/7 + 4/7
           5/7 + 1/7 = 6/7
          6/7 + 4/7 = 10/7 or 1 3/7

Jane has 18 juice boxes, 24 bags of peanuts and 36 apples. She wants to make snack bags with same number of each thing in each b
pishuonlain [190]

Answer:  6 snack bags.

Step-by-step explanation:

For this exercise it is important to remember the Greatest Common Divisor (GCD). This is defined as  the largest positive intener by which  you can divided evenly "n" numbers.

In  this case, you know that Jane has  18 juice boxes, 24 bags of peanuts and 36 apples. Therefore, the steps are the following:

1. You need to descompose 18, 24 and 36 into their prime factors, as below:

18=2*3*3=2*3^2\\\\24=2*2*2*3=2^3*3\\\\36=2*2*3*3=2^2*3^2

2. Now you must choose the common ones with the smallest exponent and multiply them.

Then, you get:

GCD=3*2\\\\GCD=6

Therefore, the greatest number of snack bags that Jane can make is:  6 snack bags.
