If x2 +8x-4=x2+8, then 2x-3+?

Mathematics
1 answer:
DanielleElmas [232]3 years ago
3 0

Answer: The number 0

x^2 + 8x - 4 = x^2 + 8

8x - 4 = 8 ... subtract x^2 from both sides

8x = 12 .... add 4 to both sides

x = 12/8 .... divide both sides by 8

x = 3/2 ... reduce

x = 1.5 .... convert to decimal form

Now plug x = 1.5 into the expression 2x-3 and simplify

2x-3 = 2*1.5-3 = 3-3 = 0 which is the answer

The sum of 3 consecutive odd numbers is 183 whats the second number im this sentence​
Naddik [55]

Answer:

The second number is 61

Step-by-step explanation:

It's implied that the first integer is odd.

Since the consecutive intergers are odd, use an equation that looks like this:

(x+2) + (x+2) + (x+2) = 183 and simplify

*If you add 2 to an odd number, you get the next odd number. That's why I used 2*

3x + 6 = 183 → 3x = 177 → x = 59 which means the first integer is 59. The consecutive integers is 59, 61, 63.

Vera_Pavlovna [14]

Answer:84 degrees

Step-by-step explanation:

so if a triangle is 180 degrees in total you need to find how much you need to equal that so you add 59+37=96 degrees so then you will subtract 180-96=84 degrees
