The first two negatives cancel out and you're left with positive 4. Now go inside the square root and do the exponent. -4*-4 = 16. Then do the -4*3*1 = -12. Do 16-12 = 4. now the square root of 4 = 2. at the dominator is 2*3 = 6. right now they problem should look like 4+- 2/ 6. from there you split the problem in two. so you have 4+2/6   &     4-2/6     then you solve both problems.
           6/6               2/6
             1                  1/3
1 & 1/3 are your answers. I hope this helped!

One number is 7 less than another. If 4 times the smaller number plus 2 times the larger number is 62, find the two numbers.
Nana76 [90]
X=Y-7

4X+2Y=62

4(Y-7)+2Y=62

4Y-28+2Y=62

6Y=62+28

6Y=90

Y=90/6

Y=15
Larger number^

X=15-7=8
Smaller number^
PROOF:
4*8+2*15=62

32+30=62

62=62
Hope this helps.

Could someone maybe explain to me what I need to do here? Please? I would love you forever! Lol, I need help.....
Maurinko [17]

Answer:

If you cut along the dotted line and remove the pieces you cut off, fold the sides inward and you get a moving box.

Each dotted line is 2 feet long, and each un-dotted line is also two feet.

Good luck, I hope this helps because honestly I just tried to figure it out for an hour. Lol.

Assoli18 [71]

the percent increase in the price of a gallon of milk from 1985 to 2005 is 59%

Define percent increase

Percent increase can be described as the rise in the value of an item, in this case the value is milk.

Write out the parameters

In 1985 the price of a gallon of milk is $2.20

In 2005 the price is $3.50

Formula for percent increase

new price-old price/new price × 100

Calculate the percent increase

new price= $3.50

old price= $2.20

= 3.50-2.20/2.20

= 1.3/2.20

= 0.59 × 100

= 59%

Hence the percent increase from 1985 t0 2005 is 59%
