2(4+2x)25x+5 = 300x + 5
2(4+2)•25x+5
2(4+2)•25x=300x
= 300x + 5
Answer:
A; ?; Line 3
Step-by-step explanation:
Question 1:
-30 divided by -6 is 5.
The negatives cancel each other out.
And 30 divided by 6 is simply 5.
Question 2:
Do the operation inside the parenthesis first:
Divide. 12 does not go into 62 evenly. 12 times 5 is 60, so the answer is 5 remainder 2:
Or in fractions:
(Was there a typo? From what you've given me, the correct answer is not listed.)
Question 3:
So we have to following steps:
The mistake is in Line 3. Danny cannot just combine 5+6(2) into 11(2). Instead, he should multiply 6(2) and then add. Thus, the correct solution is:

Answer to Question 2:</h3>
The answer to question 2 is 8x - 37
Step-by-step explanation:
Firstly, do the distributive property to simplify the terms within the bracket.
4(2x + 10) -3 ---> 8x + 40 - 3
Next, combine like terms
8x + 40 - 3 ---> <u>8x - 37</u>
<em>That's All!</em>

Answer to Question 3:</h3>
The answer to question 3 is 6(4c−3)
Step-by-step explanation:
Firstly, find the largest shared factor of 24 and 18, in the equation 24c−18
24: 1,2,3,4,6,8,12,24
18: 1,2,3,6,9,18
The largest between both of them is 6.
Next Step, divide both terms in the equation by 6.
24c−18 ---> 4c-3
Lastly, add brackets add a 6 on the outside of them.
4c-3 ---> 6(4c-3)
<em>That's All!</em>
5+5x = x^2 +9
x^2 -5x +4 =0
(x-4)(x-1)=0
x-4=0
x_1=4
and x-1=0
x_2=1
