Answer:

-(1/10)x

Step-by-step explanation:

This is an addition problem. Since the variable (x) is the same in both terms, we need only sum up the coefficients -3/5 and 1/2 and then multiply x by this sum.

-3/5x+1/2x = (-3/5 + 1/2)x

The LCD of -3/5 and 1/2 is 10. The -3/5 term converts to -6/10 and the 1/2 term to 5/10. Thus, we have (-6/10 + 5/10)x = -(1/10)x

Solve the equation by factoring: x^2 - 5x = 14

daser333 [38]

Answer:

x=7, x= -2

Step-by-step explanation:

Start by putting the whole equation to one side: x2-5x=14 ----> x2-5x-14=0
Next, factor the equation: x,x -7,2 ----> (x-7)(x+2)=0
Now, solve both equations: x-7=0....x=7 AND x+2=0.....x= -2
Plug both in to make sure that they are correct....both are correct

Answer:

The correct answer is 64 times Geri’s original answer

Step-by-step explanation:

Given

Gari's Answer: 2³

Correct Answer: 2⁹

Required:

Relationship between both answers

Let Gari's answer be represented by G and the Correct answer be represented by C; Such that

G = 2³

C = 2⁹

Divide C by G

$\frac{C}{G} = \frac{2^9}{2^3}$

From law of indices, $\frac{a^m}{a^n} = a^{m-n}$

Applying this law, we have

$\frac{C}{G} = 2^{9-3}$

$\frac{C}{G} = 2^{6}$

$\frac{C}{G} = 2*2*2*2*2*2$

$\frac{C}{G} = 64$

Multiply both sides by G

$G * \frac{C}{G} = 64 * G$

$C = 64G$

Hence, we can conclude that the correct answer is 64 times Geri’s original answer

To get the answer you have to fill in the 14 for r because that is the radius. Then multiply 14 by it self to get 196 then multiply that by pie to get your answer of 615.75216.

So the answer is 615.75216
