Answer:
Step-by-step explanation:
14 times a number x : 14* x = 14x
Quotient of 14 times a number x an 9 : 
5 less the quotient of 14 times a number x and 9 :
Expression with parenthesis: = 2 ( l + w)
Expression without parenthesis = 2l + 2w
The property we used is known as "Distributive Property"
Let, width = w
Length = w + 70
Perimeter would be: P = 2(w+70+w)
p = 2(2w+70)
p = 4w + 140

Answer:
A
Step-by-step explanation:
Answer:
y-intercept is 10
slope of line is 7
Explanation:
The general form of the linear equation is:
y = mx + c
where:
m is the slope
c is the y-intercept
Now, the given equation is:
y = 7x + 10
Comparing the given equation with the general form, we will find that:
m = 7 .............> This means that the slope of the line is 7
c = 10 ............> This means that the y-intercept is 10
Now, the y-intercept here means that the initial number of points at time = 0 (x=0) is 10 points.
The slope here means that the rate increases by 7 points each second
Hope this helps :)
