Answer:
Step-by-step explanation:
4y2 - 2x + 7 + 2y for x = 7 and y =2.
= 4(2)^2 -2(7) +7 + 2(2)
= 4(4) - 14 +7 + 4
= 16 - 14 + 7 + 4
= 13
Step-by-step explanation: 8x+2y=0 move variabe to the right
next divide both sides by 2 and that gives you 2y =-8x to get the answer that is y= -4x

Answer:
7, 24, 26
Step-by-step explanation:
6 squared is 36 and 8 squared is 64. Add them together and you get 100, which is 10 squared. Do the same for the other ones and you'll notice that 7 squared and 24 squared added together is 625, which is not 26 squared. In my head 25 squared is 625(check if you don't believe me) so I know that the answer is the third one. The basic formula for a right triangle is a^2 + b^2 = c^2, and that's how you find if three numbers form a right triangle or not. Hope this helps :)
Let's convert them to decimals:
1/25 = 0.04
4% = 0.04
0.04 = 0.04
0.4 = 0.40.
So 0.4 is NOT equivalent to the other values.
