Which expressions are equivalent to 16x4 − 64? Check all that apply. 16x4 + 16x – 16x – 64 16x4 – 8x – 8x – 64 (4x2 + 8)(4x2 – 8) 16(x2 + 2)(x2 – 2) 4(4x4 – 8)

Answers

The given expression is $16x^(4)-64.$

It can be written as $16x^(4)+16x-16x-64.$ [ we can add or subtract the same thing]

The expression can be factored as difference of two squares

$16x^(4)-64=[4x]^(2)-(8)^(2)=(4x^(2)+8)(4x^(2)-8)$

The common factor of the two terms is 16

WE can take 16 as common factor: $16x^(4)-64=16[x^(2)-2^(2)]$

= $16(x^(2)+2)(x^(2)-2)$

Options 1 ,3,4 are the equivalent expressions.

16x^4 - 64

equivalent expressions are :
16x^4 + 16x - 16x - 64
(4x^2 + 8)(4x^2 - 8)
16(x^2 + 2)(x^2 - 2)

Stu hiked a trail at an average rate of 3 miles per hour. He ran back on the same trail at an average rate of 5 miles per hour. He traveled for a total of 3 hours.Which equation can be used to find the time it took Stu to hike the trail?

3t = 5
3t = 5(3 – t)
3 + t = 5 + (3 – t)
3t + 5(3 – t) = 3

Answers

Answer:

The correct answer:

B.) 3t = 5(3 – t)

Step-by-step explanation:

Drag each tile to the correct cell in the table.

Trip to end of trail — 3, t, 3t

Trip back — 5, 3 - t, 5(3 - t)

Tap the THANKS button and RATE ⭐️

(If helpful)

Final answer:

For a problem involving distance, rate, and time, the equation 3t + 5(3 - t) = 3 can be used to find the time it took for Stu to hike the trail. In it, 't' is the time hiking, and the equation represents the total distance he traveled set equal to his total travel time

Explanation:

For this kind of problem, it is key to remember that distance is equal to speed times time (this is often stated as distance = rate x time or d = rt). In this case, you need to find the time it took Stu to hike the trail. As Stu hiked at an average rate of 3 miles/hour and ran at a faster speed of 5 miles/hour, we can create the equation in terms of 't', where 't' is the time it takes to hike.

Because the total time he was traveling (hiking and running) is 3 hours, the correct equation is 3t + 5(3 – t) = 3. This equation represents the distance that Stu hiked (3t) plus the distance that he ran (5 times the remaining time), equaling the total distance that he traveled. To solve for 't', you would set these two terms equal to the total travel time of 3 hours.

Maria is selling toys an flowers.The toys cost $12 an the flowers cost $10. She needs to make at least $300.

Answers

Maria needs to sell at last 14 flowers and 14 toys to get $308

I will show you how it works:
x(12+10) = 300 you add 12 and 10 together
x(22) = 300 than 22 times x
22x = 300 now you divide 300 by 22, you will get 13.64, round it, 14
x = 14

Flowers : 10 times 14 = $ 140
Toys : 12 times 14 = $168 Now add them together.
Flowers and Toys = $308

So this is how you get the answer

Answer:

3.195

Step-by-step explanation:

Answer:

To solve this equation, you need to multiply each term separately and then add them up.

3 × 1 = 3 1 × 1/10 = 1/10 9 × 1/100 = 9/100 5 × 1/1000 = 5/1000

Now we can add them all together:

3 + 1/10 + 9/100 + 5/1000 = 3 + 0.1 + 0.09 + 0.005

Simplifying the decimals, we get:

3 + 0.1 + 0.09 + 0.005 = 3.1 + 0.09 + 0.005

Adding the decimals gives:

3.1 + 0.09 + 0.005 = 3.195

Therefore, the solution to the equation is 3.195.
