Set up equations like this (keep in mind that perimeter of a rectangle is all sides added up, so two lengths and two widths):
2l + 2w = 340
l = w + 10
Plug (w + 10) in for l in the first equation and solve for w:
2(w + 10) + 2w = 340
2w + 20 + 2w = 340
4w + 20 = 340
4w = 320
w = 80
The width of the field is 80 yd. Plug 80 in for w in either equation:
l = 80 + 10
l = 90
The length of the field is 90 yd.
Answer:
26.24, 13.12, 6.56, 3.28
Step-by-step explanation:
Divide the previous term with 2 to get next term. here is another pattern that is ending with 3.28
Always will be your answer ;D
Answer:
x= -7
The whole thing is just an awkward mirror but the lower triangle has an angle that is 1 degree smaller so the whole lower section is going to be bigger or smaller and the angle that mirrors the 80 degree angle is now 79 degrees which makes the other angle on that line 1 degree bigger which would be 101 so you put it in the expession to make it the equation -12x+17=101 and you solve for x which you would then get -7.
