210 = 21 times 10 = 7 times 3 times 5 times 2 252 = 126 times 2 = 63 times 2 times 2 = 21 times 3 times 2 times 2 = 7 times 3 times 3 times 2 times 2 = 7 times 3^2 times 2^2
PLEASE HELP I GIVE THANKS
Answers
4x+(3x-8)=90
4x+3x-8=90
7x=98
x=98/7
x=14
If x=14,
angle CDJ is:
(3(14)-8) degrees
=34 degrees
4x 3x -8 angle ADJ is a right angle, so it is equal to 90 degrees. so if you added the two missing numbers together (4x and 3x-8) it would have to equal 90. 4x+3x-8=90 7x-8=90 7x=98 x=14. plug x back into the equations to find your angles. 3(14)-8 and 4(14)
Why are 1,4,9,16,and 25 sometimes are called perfect square please HELP ME!!!!!!
Answers
They are all perfect squares because if you took the square root of them you will get a single number. Like the square root of 25 is 5 bc 5(5) is 25 16 is 4 bc 4(4) is 16 9 is 3 bc 3(3) is 9 1 is 1 bc 1(1) is 1 & so on & so forth
