Which constant term should be used to complete the square? x^2-5x+__=7

1 answer:

7 0

The constant term should be (-5/2)^2 or (5/2)^2 or 25/4. This constant term comes from taking the coefficient on the x^1 term, halving it, and then squaring it.

Answer:

8 triangles

Step-by-step explanation:

I took this question to mean that we have the lengths, 2, 6, and 7 and have multiple copies of them. Using these lengths, what are all of the triangles that can be made?

2x2x2

6x6x6

7x7x7

2x6x7

6x6x7

6x7x7

2x6x6

2x7x7

2x2x6 and 2x2x7 don’t make a triangle.

So, 8 triangles can be made.

The complete question in the attached figure

we know that
[volume of a prism]=L*W*H

<span>first type of prism measures 3 inches by 6 inches by 14 inches
</span>then
[volume first type of a prism ]=3*6*14----------> 252 in³

second type of prism measures 15 inches by 5 inches by 10 inches
then
[volume second type of a prism ]=15*5*10----------> 750 in³

[volume of the figure]=2*[volume first type of a prism ]+[volume second type of a prism ]

[volume of the figure]=2*252+750---------> 1254 in³

the answer is 1254 in³
