Answer:
4x^2 +84x+440
840 in^2
Step-by-step explanation:
The length of the picture and frame is x+ 22+x= 2x+22
The width of the picture and frame is x +20+x = 2x+20
Area is length times width
A = (2x+22) *(2x+20)
We can FOIL to find the area
first 2x*2x = 4x^2
outer 2x*20 =40x
inner 2x*22 = 44x
last = 22*20 = 440
Add these together
4x^2 +40x+44x+440
4x^2 +84x+440
b. x=4
4x^2 +84x+440
4(4)^2 +84(4) +440
4*16 +336+440
64+776
840

Answer: <u><em>$7.29</em></u>
Step-by-step explanation: First you need to multiply 3 by 2.25 because you are buying 3 bags of takis. → 3*2.25= $6.75
Then you need to turn 8%a decimal. 8 percent is 8 out of 100% thus
8/100 or .08.
You need to multiply .08 by 6.75 and then you get your answer of $7.29 for three bags of takis with a 8% tax.

1 is the answer.
27× (3×3×3)^-1
= 27× (27)^-1
=27× (1÷27)
= 27÷27
= 1
