Answer:
742
Step-by-step explanation:
27 + 31 + 35 + ...
a = 27
d = 31 - 27 = 4
S14 = (14/2)[2(27) + (14-1)(4)]
= 7(54 + 52)
= 7(106)
= 742
Answer:
Step-by-step explanation:
Answer:
The ratio of the length of the banner to the length of the sign = 54/17
So....since they are similiar figures, the widths will have the same ratio
And the ratio of the area of the banner to the area of the sign will be the square of this ratio
Step-by-step explanation:
[54/17]^2 = 2916/289
point slope form:y-2=4(x+1)
then distribute 4 and simplify y-2=4x+4 , y=4x+6 is the slope -y intercept form
then, move 4x on the left side, you get -4x+y=6 , multiply every term by -1, you get 4x-y=-6 which is standard form.
