Answer:
C) (a-12b)(a+12b)
Step-by-step explanation:
a^2-144b^2 = (a-12b)(a+12b)
This is the formula that when two terms squared are written with a minus sign between them their factors are the product of the original numbers once with a plus sign and once with the minus sign.
This can be explained by multiplying them.
(a-12b)
<u> *(a+12b) </u>
a²- 12ab
<u> +12ab - 144b² </u>
<u> a² +0 - 144b² </u>
We see we get the same answer as applying the formula above.
Answer:
A
Step-by-step explanation:
Because 7000*1.09= 7630
and 5000*1.11= 5550 which are both equal to the amount each account will have after one year where they have gained interest.
In the first account 7630-7000=630 and the second 5550-5000=550
which is how much each gained in interest. together that makes 630+550=1180 in interest.

Step-by-step explanation:
Answer:
x=45
y=30
Step-by-step explanation:
We know that there are two isosceles triangles which means two of the angles in the triangle are equivalent. We can use this to first solve for x
180-90=2x (This is for the smaller triangle)
90=2x
x=45
Now we find the measure of the angle in the bigger triangle.
(180-30)/2=150/2=75
Since y+x=75
y=75-x
y=75-45
y=30
