Add the percentage as a decimal
To 1 to get 1.20
Multiply:
340 x 1.20 = 408
Answer: 408
19(3) + 17(2) = 91 and 91 is not equal to 55
19(3) +17(-2) = 23 and 23 is not equal to 55
19(2) + 17(1) = 55 and also 17(2) + 19(1) = 53
So the answer is C.
Hope this helped :)
Y = x² + 1
y = x + 1
x² + 1 = x + 1
<u> - 1 - 1</u>
x² = x
x² - x = 0
x² + 0x - x - 1 = 0
(x - 1)(x + 0) = 0
x - 1 = 0 or x + 0 = 0
<u> + 1 + 1</u> <u> - 0 - 0</u>
x = 1 x = 0
