Answer:
you would multiply the price by .20
Step-by-step explanation:
example:
20% of $160
sale, 20% off
160 x .20 = 32
$32 is 20% of $160, $128 is the sale price
Answer:
b) -10
Step-by-step explanation:
x^2 + 3x + k = (x - 2)(x - a)
(x - 2)(x - a) = x^2 - 2x - ax + 2a = x^2 + [-2 - a)x] + 2a
-2 - a = 3
2a = k
a = -5
k = 2(-5) = -10
Answer: b) -10
Answer:
I can help you with C and I tis non-linear because to make it linear it needs to be a straight line and shouldn't have any curves.
Step-by-step explanation:
Answer: Only 21:72:87
Explanation: We know that the side lengths are not simply 7, 24, and 29, as the sum of these is only 60.
Therefore, we need to find the scale factor they were multiplied by to have side lengths with a sum of 180.
We can use 7x+24x+29x=180.
This becomes 60x=180 and the scale factor is x=3.
7*3=21, 24*3=72, and 29*3=87.
