all u are doing is adding them up
Substitute y=4x to the second equation:
x^2 + (4x)^2 = 17
x^2 + 16x^2 = 17
17x^2 = 17
x^2 = 17/17
x^2 = 1
x = 1 and -1
When x=1, y=4(1) = 4
When x=-1, y=4(-1) = -4
Thus the solutions would be (1,4) and (-1,-4). That would correspond to D. and A.
Answer: No you can not make any triangles with 2 inches, 2 inches and 4 inches. hoped this helped!
Step-by-step explanation:
First we write it into scientific notation which is 3.5*10^7. now it's order of magnitude is power of 10 that is 7. So order is 7.
