The width can be x.
so it means that the length is 2x
the equation would be
    2(x+2x)=24 inches
    2x+4x= 24
      6x= 24
       x=4 (this is  the width, so the length will be 8 inches)
the area will be 4 times 8 = 32

4. Give an example of a like term for each of the following: a. 144 b. -95 c. 200 d. h²​
Luda [366]

Answer: 1, -2, 3, 2h^{2}

Step-by-step explanation:

what is... a LIKE TERM????

a like term is a term that you can easily combine in an algebra equation. you can combine them because they share the same terms. FOR EXAMPLE.... YOU CAN COMBINE THESE ON THE LEFT SIDE OF THE EQUAL SIGN:

2x+3x=0

to

5x=0

so for a, b, and c... its basically any number that doesnt have a variable attached to it. THEY COULD BE ANYTHING. like 1, -2, and 3. but for d... its a different story.... because there is h^{2} so a like term could be 2h^{2}

notice that i wrote -2 for b... well theoretically it doesnt even have to be negative because you can combine a negative integer with a positive integer! i just made it negative for convenience....

Rock musician Donny West is paid 15% on his CD sales and tour video sales. Last year, he sold one million CDs and 550,000 videos
Likurg_2 [28]

Answer:

Total amount of CD sales was $750,000.

Step-by-step explanation:

one million CDs were sold at $5/CD.

1,000,000 × $5 = $5,000,000

Donny gets 15% of the sales, so he'll receive the amount of CD sales as:

$5,000,000 × 15/100 = $50,000 × 15 = $750,000.

Optional:

If you add both of the multiplied values, 1,000,000 × 5 + 550,000 × 6

= $5,000,000 + $3,300,000

= $8,300,000

so, 15% of it would be $1,245,000.

if you calculate both separately and then add them, you'll still get $1,245,000.

I hope this'll help.

H(x) = 2x^2 =4; Find h(-10)
bogdanovich [222]

For this case we have the following function:

h (x) = 2x ^ 2 + 4

We must find the value of the function when x = -10

So, replacing we have:

h (-10) = 2 (-10) ^ 2 + 4\\h (-10) = 2 (100) +4\\h (-10) = 200 + 4\\h (-10) = 204

Thus, the value of the function is 204 when x = -10

Answer:

h (-10) = 204
