I dont think the answer is 129 unless you typed the problem in wrong. Order of operations say to do everything inside the perenthesis first so you would do the 3*2 which is 6 then divide the 12 by 6 and you get 2. so your new equation is 8^2+9(2)-7. Next distribute the 9 to the 2 that is inside the perenthesis. Square root the 8 also. Now it is 49+18-7. The answer would be 60 ...?
Answer:
32.04% to 2 decimal places.
Step-by-step explanation:
As a fraction it is 17.3 / 54
To get the percentage we multiply by 100:
= (17.3/54) * 100
= 32.04%
You have to foil out the problem
(2x+8)(2x+8)
4x^2+16x+16x+64
4x^2+32x+64
13/52= 1/4 or .25
If you have a scientific calculator it really helps with simplifying numbers to the lowest term.
