well its impossible to answer since there is no x=? if it was 5x+20=40 then x=4 5 x 4=20+20=40

3 * x + 4 + 2xMDAS rule:3x + 4 + 2x5x + 4
9Y + 4 = 2Y + 25 subtract 2Y from both sides 7Y + 4 = 25 subtract 4 from both sides 7Y = 21 divide both sides integers by 7 (7/7)Y = 21/7 Y = 3 -----------------check in original equation 9(3) + 4 = 2(3) + 25 27 + 4 = 6 + 25 31 = 31 ---------------checks
It is, as stated, x2 - 5x + 25/4 = 0
100 divided by 25 plus 8 times 4 is equal to 36.
9 plus 16=25 3 squared is the same as 3 times three and 4 squared is the same as 4 times 4 3 times 3 + 4 times 4 9 plus 16 = 25

36+4=40 40-8=32 32-25 equals=7 answer

25 + x
Times 16 times 25 = 400 now what times to 400 and adds to 40 list the things that add to 40= 5+35 = 40 but 5 times 35 is 175 so it doesn't work 10+30 = 40 but 10 times 30 is 300 so it doesn't work but going in the right direction 20 +20 = 40 and 20 times 20 is 400 so we found our factors (16X+20) (16x+20) but wait they can be divided by 4? ----------- ---------- 4 4 (Note if they can be divide by different numbers you can) (4X+5)(4x+5) is the factor of it!
