Percy solved the equation x2 + 7x + 12 = 12. His work is shown below. Is Percy correct? Explain.
Furkat [3]

Answer:

Percy is incorrect

Step-by-step explanation:

I plugged in 9 and 8 for x and both of them did NOT solve it. The only number I know of that can solve it is -7.       -7^2=49

                                             -7 multiplied by 7 =-49

                                                      (49) + (-49) + 12 = 12

Calculate s26 for the arithmetic sequence in which a14=4.1 and the common difference is d=1.7
sweet-ann [11.9K]

Answer:

The value of s_{26}=84.5

Step-by-step explanation:

We have given  a_{14}=4.1

d=1.7

We have to find s_{26}

So, a_{14}=a+13d from the formula

a_n=a+(n-1)d

When n=14

a_{14}=a+(14-1)(1.7)=a+13(1.7)

4.1=a+22.1

-18=a

a=-18

Using the formula:

s_n=\frac{n}{2}[2a+(n-1)d

When n=26

s_{26}=\frac{26}{2}[2(-18)+(26-1)(1.7)]

On simplification we get:

s_{26}=84.5
