For the answer to the question above asking wWhat is the length of a room that is 8.8 cm long and 3 cm wide on the blueprint if <span>a blueprint, the scale indicates that 8 cm represent 16 feet?
</span>The room is 22.4 feet long
8cm=16ft
9.8cm=?ft
8cm 9.8cm
______=______
16ft x ft
Cross multiply
8x=156.8
divide both sides by 8
x=19.6 ft
Hi There!

Question 2:
Obviously the right equation for this question is Point Slope Form.
Point Slope Form: y - y1 = m(x - x1)
y1 = -1
x1 = 3
m = 2
Question 2 Answer: y + 1 = 2(x - 3)
----------------------------------
Question 3:
Again use point slope form.
Find Slope:
7 - 1 = 6
-2 - 1 = -3
6/-3 = -2
Question 3 Answer: y - 1 = -2(x - 1)
----------------------------------
Hope This Helps :)
So we factor 12
remember that (-) times (-)=(+)
and
(-)+(-)=(-) so therefor the factors must be negative
factor 12
2,2,3
we have
-2 times -6 which adds to -8
-3 times -4 wihch adds to -7
the numbers are -3 and -4
4.024
Four and twenty four hundredths
