2. The length of a rectangle is 5 feet more than the width. The perimeter of the rectangle is
nevsk [136]
In order to solve this let us for at assume that the value of the width is X. Therefore the length will be x+5.

We can now write an equation:

(X+5) + (X+5) + X + X = 58

Combining like terms we should get
4X + 10 = 58

Now subtract 10 from both sides to get
4x = 48

Divide by 4 now and you should get

X = 12

Now we know the value of X and therefore the width.

Help me please. im having trouble
brilliants [131]
The blank is 3. 

What the question is assessing is the distributive property. The 3 term gets distributed to the 6 and the -2, which means it the 6 and the -2 are multiplied by 3.

If f (a.b) = f(a) + f(b) and f (2) = 3, then f (32) equals
Monica [59]
Solution:

from;  f(2)=3  
        f(2n)   nf(2)  
        (3)(n)
therefore :
f(32)=f(2.16)
f(32)=16f(2)
f(32)=(16)(3)

f(32)=48  final answer

for more details, please see the solution attached.
