We must solve for x. Let's simplify this equation by dividing both sides by 6:
|2x-14|=7, which is the same as 2|x-7|=7.
First, assume that x-7 is already positive, so that we don't need the absolute value operator. Then x-7=7/2. Adding 7 to both sides results in x = 21/2.
Next, find the other solution:
Assume that x-7 is negative. Then |x-7|=-(x-7). Then -(x-7) = 7,
and -x + 7 = 7. Thus, x = 0.
The solution set is {0, 21/2}.
Hello,
Answer A
Let's the width of the rectangle
2a-5 its length
Teh half perimeter is 80/2=40
a+2a-5=40 ==>3a=45==>a=15 and 2a-5=30-5=25

Answer:
see the explanation
Step-by-step explanation:
step 1
Find the scale factor of the dilation
Divide the x-coordinate or the y-coordinate of the image by the the x-coordinate or the y-coordinate of the pre-image
so

or

step 2
Multiply the coordinates of point B by the scale factor to obtain the image B'
B'(1.5*1,1.5*4)
B'(1.5,6)
