Answer:

46

Step-by-step explanation:

The complete square starting with x^2+14x would be x^2+14x+49, since the square would be (x+7)^2. To make this square perfect, then, you would need to add 46 to make 49 with the 3. Hope this helps!

There are 38 Cube Houses. Each house could hold 1,000 unit cubes that are 1 meter by 1 meter by 1 meter. Describe the dimensions
kvasek [131]
So each house can hold 1000 cubes that are 1 meter in length. The house is also shaped like a cube, so you need to cube-root 1000. The cube-root of 1000 is 10. So the cube house has a length, width, and height of 10 meters.

The figure below was made with a scale of 1 unit =9 m. You can place your figure anywhere on the grid on the right.
Zielflug [23.3K]

Answer & Step-by-step explanation:

I can't draw the image, but I can explain it to you.

Since 1 unit was 3 units and now it's 9, you would have to divide each side by 3. So, the width would be 1 unit and the length would be 2 units.

I hope this helped!!!

Which of the following are solutions to the equation below?
Luden [163]

Answer:

c) -4/5

d) 4/5

Step-by-step explanation:

The given equation is 25x^2 -16 = 0

Adding 16 on both sides, we get

25x^2 = 16

Dividing both sides by 25, we get

x^2 = 16/25

Taking square root on both sides, we get

x = √(16/25)

x = ±4/5

Therefore, x = 4/5 and x = -4/5

Answers: C) and D)

Hope this will helpful to understand the concept.

Thank you.
