Hi there!
Here are all the steps into simplifying this expression :
<u>(4 × 2)</u> + 15x + 49
Do the multiplication first → 4 × 2 = 8
<u>8</u> + 15x + <u>49</u>
Add the similar terms together → 8 + 49 = 57
15x + 57
Since there are no longer similar terms, the expression can not be simplified anymore and you are left with this expression as an answer :
15x + 57
There you go! I really hope this helped, if there's anything just let me know! :)

Answer:
x = - 3, x = - 1
Step-by-step explanation:
x² + 6x + 3 = 2x ( subtract 2x from both sides )
x² + 4x + 3 = 0 ← in standard form
Consider the factors of the constant term (+ 3) which sum to give the coefficient of the x- term (+ 4)
The factors are + 3 and + 1 , since
3 × 1 = 3 and 3 + 1 = 4 , then
(x + 3)(x + 1) = 0 ← in factored form
Equate each factor to zero and solve for x
x + 3 = 0 ⇒ x = - 3
x + 1 = 0 ⇒ x = - 1
The slope from a table can be found by finding what number keeps adding on new points. (horrible wording sorry)
EXAMPLE:
x y
0 2
1 4
2 6
3 8
4 10
for the X values it keeps adding by 1 and the Y values keep adding by 2. Since the slope is the change in y over x the slope would be 2/1 therefore simplifying to a slope of 2. To find the y intercept, you have to look for a value in which the X value is 0. From the table, this would be 2 so the y int is (0,2)
