<h3>Answer: Choice D</h3>

Here's why:

The 4 and 8 on the left side combine to 12. The 5x and -3x on the right hand side combine to 2x.

This means the equation for choice D becomes 2x+12 = 2x-12

From here, subtract 2x from both sides. Doing so will cancel each copy of 2x and the x terms go away entirely. We're left with 12 = -12 which is a false statement since we don't have the same number on both sides. We have a contradiction instead, so there are no solutions here.

No matter what we replace x with in equation D, it will always be false.

If you graphed y = 2x+12 and y = 2x-12, you would find that the lines are parallel. Parallel lines never intersect. Intersection points are solution points, so this is a visual way to see that we don't have any solutions.

Explain the steps that are necessary to solve 4x - 2(x + 3) = x + 1
Sidana [21]
So you would distribute what's in the parenthesis and end up with 4x-2x-6=x+1, then you combine like terms and end up with 2x-6=x+1, now you can add 6 to both sides or subtract 1 both sides (basically anything goes for this step just make sure you apply the same thing on both sides) so I'll add 6 and continue just to show you... then you end up with 2x=x+7 then you subtract 1x on both sides to get x=7. sorry it's a lot hopefully you get it know!

The perimeter of a parallelogram is 72 meters. The width of the parallelogram is 4 meters less than its length. Find the length
mafiozo [28]
Perimeter of a parallelogram = 2(l + w). But w = l - 4
Therefore, 72 = 2(l + l - 4) = 2(2l - 4) = 4l - 8
4l = 72 + 8 = 80
l = 80/4 = 20
w = 20 - 4 = 16

Therefore, length = 20 meters and width = 16 meters

Tires have a normal distribution with a mean of 70000 miles and a standard deviation of 4400 miles. What proportion of tires wil
yarga [219]
Let T = the distance, in miles, a tire lasts

T ~ N(70000,4400<span>²</span>)

P(T \geq 75000) 
 = P(Z \geq \frac{75000 - 70000}{4400})
 = P(Z \geq \frac{25}{22})
 ≈ P(Z \geq 1.14)
 = 1 - P(Z < 1.14)
 ≈ 1 - 0.8729
 = 0.1271
