Answer:
area is 84
Step-by-step explanation:
perimeter is 38(p)
length (l) is 7cm
width is?(w)
p=2(l+w)
38=2(7+w)
38=14+2w
2w=38-14
2w=24
w=12
area=l*w
12*7
=84

Answer:
<h2>32° and 58°</h2>
-by-step explanation:
Let x be the measure of angle 1
and y be the measure of angle 2
The Two angles are complementary
means
x + y = 90
their difference is 26 degrees
means
x - y = 26
x + y = 90 (1)
x - y = 26 (2)
(1) - (2) ⇒2y = 64 ⇒ y =32°
therefore x = y + 26 = 58°

I thonk it s 6 miles not sure though :-)
Let
x---------> the length of the first piece
y---------> the length of the second piece
z---------> the length of the third piece
we know that
x+y+z=72 -------> equation 1
y=x+6 -----> solve for x
x=y-6 -------> equation 2
z=6+y -------> equation 3
substitute equation 2 and equation 3 in equation 1
[y-6]+y+[6+y]=72
3y=72
y=(72/3)=24 in
<u>Find the value of x</u>
x=y-6 -------> equation 2
x=24-6=18 in
<u>Find the value of z</u>
z=6+y -------> equation 3
z=6+24=30 in
therefore
<u>the answer is</u>
the length of the first piece is 18 in
the length of the second piece 24 in
the length of the third piece is 30 in
A.. 9.5*3.6=34.2 then 34.2/5.7= 6 so 6 is your answer
B. 16.2*5.7= 92.34 then 92.34/3.6= 25.65
