35 would be the answer. 45+35=80 and 45 is 10 more than 35
2(6+w)+2(w)=40
12+2w+2w=40
12+4w=40
4w=28
w=7
Now we know that the width is 7; abd the length is 7+6 which is 13.
To find the area we multiply 13x7
The area is 92cm squared
F(-3.29) = (-3.29) + 2.58
f(-3.29) = -0.71
Answer:
x = 8
Step-by-step explanation:
3(x-4) = 12
3x - 12 = 12
+ 12 + 12
3x = 24
/ 3 / 3
x = 8
The answer is no, the side lengths are not persevered. <span />
