STEP-BY-STEP SOLUTION:

So here is the expression as displayed below:

= 3x ( 4 - 8y ) + 3 ( 2xy - 5x )

First of all, we will expand the expression as displayed below:

= 3x ( 4 - 8y ) + 3 ( 2xy - 5x )
= 12x - 24xy + 6xy - 15x

Then, we will collect like terms as displayed below:

= 12x - 24xy + 6xy - 15x
= - 3x - 18xy

After that, we will take out the common factor and factorise as displayed below:

= - 3x - 18xy
= - 3x ( 1 + 6y )

Therefore, the final answer is:

- 3x ( 1 + 6y )

the driveway in front of the brown house is 35 feet long and the driveway of the red house is 7 yards and 9 feet long. which hou
Zigmanuir [339]

Answer:

The brown house has the longer driveway

Step-by-step explanation:

So we would need to convert both of these units of measurements to feet in order to compare them.

  • There are <u>3 feet in 1 yard</u>

Converting yards to feet, wee need to multiply the number of yards by 3

  • 7 yards = 21 feet

Since the red house has a driveway of 7 yards and 9 feet, we can rewrite this to 21 feet + 9 feet, which is equivalent to 30 feet

Now comparing the two driveways, the 35 ft-long brown driveway is 5 feet longer than the 30 ft-long red driveway.

The brown house has the longer driveway

What number decreased by 3.5 equals to 12.7 ?
Snowcat [4.5K]
What number = x

x - 3.5 = 12.7

Isolate the x, add 3.5 from both sides

x - 3.5 (+3.5) = 12.7 (+3.5)

x = 12.7 (+3.5)

x = 16.2

16.2 is your answer


hope this helps
