Answer:
x = 1, -2/7
Step-by-step explanation:
You could use the quadratic equation but this can be factored into
(7x + 2) (x - 1). You can verify that by multiplying it out.
Since (7x + 2) (x - 1) = 0, if either factor is 0 then the equation would be equal to 0, thus we get x = 1, -2/7
Use pi•r^2 for the formula of a circle. filling it in, you get 3.14•64 which is 200.96
Answer:
I believe the answer is six-hundred thousand (600000). That's if I read your question right. I'm not sure what you were asking exactly.
Step-by-step explanation:
6 (10000 x 10)
6 (100000)
600000
Answer:
The student is correct.
Step-by-step explanation:
Given that 5x² = 20:
It is true that the value of x = 2 because 2² = 4, and when you multiply 4 with 5, you'll get a product of 20:
5x² = 20
5(2)² = 20
5(4) = 20
20 = 20
Therefore, the student is correct that x = 2.
