2/3[8(5-2)^{2}+3*2] How do I distribute the 2/3 and then solve the rest?

1 answer:

6 0

Before I distribute, I solve the inside first:

2/3[8(3)^2+6]

2/3[8(9)+6]

2/3[72+6]

2/3[78]

2*26= 52 is the answer

another way:

2/3[8(3)^2+6]

2/3[8(9)+6]

2/3[72+6]

(2/3)*72+(2/3)*6

2*24+2*2
48+4= 52

Find the lowest common denominator of the following fractions.5/n-2 and n+2/ n^2-4 n - 2 n2 - 4 (n - 2)(n2 - 4)

DanielleElmas [232]

Answer:

(n-2)(n+2)

Step-by-step explanation:

The denominator of the second fraction is the difference of squares, so can be factored using the formula for that.

(n^2 -4) = (n -2)(n +2)

Now, you will note that the second fraction has a numerator that is equal to one of the factors in the denominator. In other words, the whole fraction can be simplified to ...

(n +2)/((n +2)(n -2)) = 1/(n -2) . . . . with the restriction n≠-2

This reduced form of the fraction has the same denominator as the first fraction, so you can say that the lowest common denominator is that: (n -2).

If there is some reason you don't want to reduce the second fraction, the lowest common denominator will be (n -2)(n +2).

$65.67

Given, Komal bought 3 shirts for $11.21 each.

She also spent her money on a keychain for $2.40 and a mug for $6.47.

After that she spent $23.17 for getting her picture developed.

How much in total she spend her money = ?

Money spent on shirts:

Cost for one shirt = $11.21

cost for three shirts = 3 × 11.21

= $33.63

Now add the amount of all the items Komal bought for herself.

Total money spent = cost price of shirts + cost price for a keychain + cost price for a mug + cost price for getting a picture developed.

Total money spent = 33.63 + 2.40 + 6.47 + 23.17

Total money spent = $65.67

Hence the total money Komal spent is $65.67.
