Answer:
<u>(x + 3)(x - 7)</u>
<u>(x + 1)(x - 2)</u>
Step-by-step explanation:
The general form of factored equations :
<u>y = (x + a)(x + b)</u> [it can be ±, so don't worry about that part]
===============================================================
Hence, the expressions which are in factored form :
⇒ <u>(x + 3)(x - 7)</u>
⇒ <u>(x + 1)(x - 2)</u>
from the question, (-2,2) and (1,2) have the same y value so you can use that as your base and easily find the perpendicular height using the y axis since it's parallel to the x axis.
the third point, (0,-6), to the base is your height
use the sum of the positive of the y values to find your height (because height can't be negative): 6+2 = 8
area of a triangle = 1/2 bh = 1/2 x 3 x 8 = 12
Note: 1/2 bh only works because (-2,2) and (1,2) form a line parallel to the x axis
Answer:
1 pound
Step-by-step explanation:
Answer:
Rs 17280
Step-by-step explanation:
percentage she spends = 12% + 64% = 76%
pencetage she saves = 100% - 76% = 24%
24% of 72000 = 17280
