-2/5n = -30 n= can some one help pleaasee

Mathematics
1 answer:
kirill115 [55]3 years ago
4 0
-2/5n=-30n
multiply both sides by -1 sinc I don' like negatives
2/5n=30n
multipl yboth sides by 5/2
1n=150/2n
n=75n
this is obviously false, the only number that would work is 0 since 0 =0 times 75

n=0

Which could be the area of the base of the triangular prism?     [Not drawn to scale]6 ft210 ft212 ft220 ft2
Alexus [3.1K]
For this case, the first thing we must observe is that the base of the prism is a triangle.
 The area of the triangle is given by:
 A = (1/2) * (b) * (h)

 Where,
 b: base of the triangle
 h: height of the triangle
 Substituting values we have:
 A = (1/2) * (4) * (3)

A = 6 ft ^ 2
 Answer:
 
The area of the base of the triangular prism could be:
 
A = 6 ft ^ 2

HELPPPPPPPPPPPPPPPPPPPPPPPPPPPP! Is 16x^2 - 56x + 49 a perfect square trinomial? How do you know? If it is, factor the expressio
jasenka [17]

No need to fear, thehotdogman93 is here!

The first step is to get rid of those very large numbers. It's going to be very difficult to factor unless we can bring those high numbers down. So lets see if we can factor each term.

So after dividing 49 with every single digit. The only number that divides evenly is 7 and one, and 16 isnt divisible evenly by 7 so that didn't work. Looks like we're gonna have to work with these big numbers.

There is something interesting though about these numbers. 16 and 49 are both perfect squares. 16 is the same as 4^2 and 49 is the same as 7^2. So we can factor the whole trinomial as:

{(4x - 7)}^{2}

If we were to expand this out as:

(4x - 7)(4x - 7)

and multiply it back into the original form. It would match with the expression we started with. The 4's would multiply back into 16x^2 and the 7's would multiply back into 49.

Additionally 4 * -7 is -28, so you can combine two -28x's into the -56x term in the original trinomial.

Thus, the answer is yes you can, and the answer is:

{(4x - 7)}^{2}
