Answer:
The answer is B
Step-by-step explanation:
i took the test and got it right on edge Give me brainiest please :)
X/8 + 12 = 16
start by subtracting twelve from both sides
x/8 + 12 = 16
- 12 -12
You're left with x/8 = 4
Multiply both sides by 8
8× x/8 = 4 ×8
Your answer is x = 32
If you need to simplify, the answer is 2.
Answer:
1 3/4 = 7/4 = 1.75
Step-by-step explanation:
The process to arrive to the solution is explained in the pictures below.
Tyler needed to convert the mixed fraction
2 1/2 = (4+1)/2 = 5/2
If we multiply by 2 numerator and denominator
5*2/2*2 = 10/4
We substract
10/4 - 3/4 = 7/4 = 1.75
Answer:
Step-by-step explanation:
A 2nd order polynomial such as this one will have 2 roots; a 3rd order polynomial 3 roots, and so on.
The quadratic formula is one of the faster ways (in this situation, at least) in which to find the roots. From 2x^2 + 4x + 7 we get a = 2, b = 4 and c = 7.
Then the discriminant is b^2 - 4ac, or, here, 4^2 - 4(2)(7), or -40. Because the discriminant is negative, we know that the roots will be complex and unequal.
Using the quadratic formula:
-4 ±√[-40] -4 ± 2i√10
x = ------------------ = ------------------
4 4
-2 ± i√10
Thus, the roots are x = ------------------
2
-x-8y+5
Hope this helps, we have same name btw
