Show your work x2 – 2x – 35 = 0

Mathematics
1 answer:
Tpy6a [65]3 years ago
8 0

Answer:

x=7     x=-5

Step-by-step explanation:

x^2 – 2x – 35 = 0

Factor

What 2 numbers multiply to -35 and add to -2

-7*5 = -35

-7+5 = -2

(x-7) (x+5) =0

Using the zero product property

x-7 =0       x+5=0

x-7+7=0+7      x+5-5=0-5

x=7     x=-5

The infinite sequence 1, 6, 15, 28, 45, ... exhibits which pattern? multiply the term number by 2, subtract 1 from the result, m
Amanda [17]
The correct response is ;
<span>multiply the term number by 2, subtract 1 from the result, multiply by 2 times the term number, and divide the result by 2.
if term number is x,
the number in the pattern for xth term is ;
multiply term number by 2 - 2x
subtract 1 - 2x - 1
multiply by 2 times the term number - (2x-1) * 2x
divide by 2 - (</span>(2x-1) * 2x)/2
so first term x=1
((2*1-1) * 2*1)/2
2/2 = 1
second term x = 2
((2*2-1) * 2*2)/2
(3*4)/2 = 6
third term x = 3
((2*3-1) * 2*3)/2
5*6/2 = 15
fourth term  x= 4
((2*4-1) * 2*4)/2
56/2 = 28
Therefore the above response shows the correct pattern

Answer: Add to eliminate x

Step-by-step explanation:

So if you add to 2 equations you can look at it this way. remove all variables right that leaves you with 10+4=48 and -10-3=-56 right and if you add 10 and -10 you get 0 or 0x so by adding these to equations x is eliminated by adding

The side lengths 10, 14, and 15 form a triangle. Explain why.​
sertanlavr [38]

Answer:

Therefore, the side lengths 10, 14, and 15 form a triangle.

Step-by-step explanation:

The Triangle Inequality Theorem defines that if we are given the three sides of a triangle, then the sum of any 2 sides of a triangle must be greater than the measure of the third side of the triangle.

The three conditions that need to be met for any triangle with the side lengths A, B, and C.

A + B > C

B + C > A

A + C > B

Given the side lengths of a triangle

  • 10
  • 14
  • 15

Let us check whether it satisfies the three conditions.

10+15 > 14     →  TRUE

10+14 > 15     →  TRUE

14+15 > 10    →  TRUE

As all the conditions are met. Therefore, the side lengths 10, 14, and 15 form a triangle.
