hope this helped plz give me brainliest! <3
Okay so first you want to simplify the given equation (7x+3y)(7x-3y)
in order to do this you multiply the first number of the first equation (7x) with the first number of the second equation (7x) this gives you 49x^2
Now you want to multiply the second number of the first equation (3y) by the second number of the second equation (-3y) this gives you -9y^2
Its as easy as pie!
As per the isosceles triangle theorem, if the two base angles are congruent then the legs are also congruent, so we must set the two legs equal to each other:
2z - 15 = 9
Add 15 to both sides:
15 - 15 = 0
15 + 9 = 24
Divide 2 from each side:
2z = 24
2z/2 = z
24/2 = 12
z = 12
Hence, the answer would be D: z = 12
89/100 as a precent is is 89% because if you change 89/100 to a decimal you get .89 and then you multiply that by 100 (or just move the decimal over 2 places to the right) and you will get 89% make since? and its the same way if your going from % to decimal except you divide by 100( or move the decimal over 2 places to the left) so to a percent is right and to a decimal is left. easy right?
Not sure on the question, love your name though. What is the question?
