Answer:
The area is 45 units squared
Step-by-step explanation:
If the rectangle's width is 3 units, and the length is 5 times then:
5 x 3 = 15
So the length is 15 units
The area is length times width
15 x 3 = 45
The area is 45 units squared
First third and last answer
Answer:
210=85+125-x+25
x= 235-210
x=25 failled in both
Step-by-step explanation:
We have that
<span>a*(3x-8)=b-18x
3ax-8a=18x+b
</span><span>The only way for this to happen (non-trivially) is if the coefficients of x are equal, and the constant terms are equal
</span>so
3ax=18x-----> 3a=18--------> a=6
-8a=b---------> b=-8*6-------> b=-48
the answer is
a=6
b=-48
Step-by-step explanation:
3u+6=22
3u=16
u=16/3
