Without a given value for "n" you cannot solve the expression. If this was an equation, like -2/3n=7/3, then you could solve for n, but without an equals sign all you can do is simplify the expression.

Factor out a negative -1/3

[tex]- \frac{1}{3} [/tex](2n-7) is your most simplified expression. Does that answer your question?

Adam is building birdhouses that requires 1/2-ft-long boards. How many pieces that are exactly 1/2 ft long can be made from a bo
Julli [10]

Answer:

16

Step-by-step explanation:

Adam is building birdhouses that requires \frac{1}{2} i.e 0.5 feet long boards.

Now, he has an 8\dfrac{1}{4} i.e. 8.25 feet longboard and wants to cut each 0.5 feet longboards.

We have to calculate the number of pieces of exactly 0.5 feet length that can be made from this 8.25 feet longboard.

Now, \frac{8.25}{0.5}= 16.5

So, there can be 16 whole board of exact length 0.5 feet. (Answer)

Total Area: T.A.=2*Ab+Al

Area of the base: Ab=p*K

Semi-perimeter of the base: p
p=P/2
Perimeter of the base: P=20
p=P/2=20/2→p=10
Ab=p*k=10*K→Ab=10K

Lateral Area of the prism: Al
Al=P*h
Height of the prism: h=6
Al=P*h=20*6→
Al=120

T.A.=2*Ab+Al
T.A.=2*(10K)+120
T.A.=20K+120
T.A.=120+20K

Answer: (120+20K)
