Lets take a look at the options first.
option 1 and option 4 are not possible as (8x) (8x) would give us 64x^2, which is not what we want.
we’re left with option 2 & 3. when expanded, option 2 will look like :
16x^2 - 40x - 10x + 25
= 16x^2 - 50x + 25
however, we do not want the 50x. so the answer is option 3, (4x-5) (4x+5)
if you don’t want to find the answer using expanding, there is also another method of expanding.
(a+b)^2 = a^2 - b^2
in this case, 16x^2 will be a^2 and 25 will be b^2. not sure whether you’ve learn this but yea.
A is on the graph. When you plug in 3 in for x you get -4
B is not. When 1 is plugged in you do notnget 4
(-11,-19) all you have to do is make one variable like x the same in both equations and so they cancel out, then you can solve for y...and to get x, once you have the final answer for y...plug that into the equation and then solve x.
Answer:
He would make $234.00.
Step-by-step explanation:
Divide $169 by 13 hours, this will tell you how much money he earns every hour. $169 divided by 13 = $13. Now, you know that Adbul makes $13 per hour. Then, multiply $13 by 18 hours of work. $13 x 18 = $234.00.
That is your answer!
you need to change 1 3/8 into a mixed fraction, which would be 11/8, but with this fraction, you need to do the reciprocal, which would be 8/11 multiplied by 3/4. You can cross simplify 8 and 4 changing the fractions being multiplied to 2/11 and 3/1. Then you need to multiply straight across, which would get an answer of 6/11.
