The proportion would go as follows:

2   C
5 = 145      Its hard to type that but 2 would go over the 5 and an equals sign would be in the middle, then C over 45. To solve then take 145 times 2 and divide it by 5.
Hope this helps.

Can someone help me with this<br> S=?
MAXImum [283]

Answer:

In order to find the value of s, we must isolate the s variable in this equation, so the first step should be subtracting 3 5/6 from both sides of this equation. In order to subtract, we multiply each denominator to get 42, and multiply the numerator by the same amount, and subtract the number from both sides:

s + 3 35/42 = 9 6/42

s = 5 13/42

Solve 2x2 + 8 = 0 by graphing the related function.
Tpy6a [65]

Answer:

The values of x are x= 2i and x= -2i

Step-by-step explanation:

We need to solve the equation:

2x^2 + 8 =0

Taking 2 common

2(x^2 +4) =0

Dividing both sides by 2

x^2+4 =0

Adding -4 on both sides

x^2 +4 -4 = 0-4

x^2 = -4

Taking square root on both sides we get

√x^2 = √-4

we know √4 = 2 and √-1 = i so answer is:

x = ± 2i

The values of x are x= 2i and x= -2i

The graph is shown in figure attached.
