RUDIKE [14]3 years ago

The easiest way to do this is to distribute one term to the second set of parentheses and add eveything. Start with x2 and distribute to get x^4 + x^3 + 2x^2. Then the 3x distributed gets you 3x^3 + 3x^2 +6x. Finally the 1 distributed gets you x^2 + x + 2. You add all three answers together to get x^4 + 4x^3 + 6x^2 + 7x + 2

Will, Mike, and Sue went to dinner. Will paid 1/3 of the dinner bill. Micah and Sue paid in the ratio 2:3. If Sue paid $6 more t
raketka [301]
Let's call their parts w,m and s

if will paid 1/3, then m+s=2w (they paid 2/3, which is twice as much as will did)

Now, we know that:
Micah and Sue paid in the ratio 2:3.
this means the 3m=2s

and m=2/3s

Again:
m+s=2w

and we substitute m:
2/3s+s=2w
5/3s=2w// multiply both sides by 3
5s=6w

we also know that s=w+6 (from the last sentence) so we substitute:

5(w+6)=6w
5w+30=6w
30=w

so, Will paid 30, Sue paid 36 (six more than him), Mike paid 24 (24:36 is the same ratio as 2:3, you can check this by dividing both 24 and 36 by 12: you have 2 and 3)

and the total was 30+36+24=90.

Set up a proportion of 12/9=8/x. Cross multiply and this gives us 12x=72. Now divide both sides by 12 and you get 6.

Which is a solution for 7 (x + 2) = 35?<br><br> A. -2<br> B. 7/33<br> C. 3 <br> D. 5<br> E. 26
enot [183]

7(x+2) = 35

Use the distributive property:

7x + 14 = 35

Subtract 14 from each side:

7x = 21

Divide both sides by 7:

x = 21 / 7

X = 3


The answer is C. 3
