5x2 - 136 = 44 5x2 - 136 + 136 = 44 + 136 5x2 = 180 5x2/5 = 180/5 x2 = 36 √x2 = √36 x = ±6
its not...
= 5x2+70-16+9x-2 = 5x2+9x+52 = 5x2+9x1+52 This implies coefficient of degree 1 is 9. Ans.
x = 8y = 6(5x8) + (3x6) = 58(5x8) - (3x6) = 22
5x2+500 = 844.45 5x2 = 844.45-500 5x2 = 344.45 x2 = 344.45/5 x2 = 68.89 x = the square root of 68.89 = 8.3 x = 8.3
x2 • (5x2 + x + 8)
5x2-8x-4
its 10
3x4-7x3+5x2-3x+6
5x2 = 3 then x2 = 3/5 so that x = sqrt(3/5) = ± 0.7746
6 + 10 = 16
To solve the equation n + 3x6 = 30, first calculate 3x6, which equals 18. Then subtract 18 from both sides of the equation to isolate n. Thus, n = 30 - 18, which simplifies to n = 12.
1) 5x2-55=90 +55 +55 2) 10x=145 /10 /10 x=14.5
5x2 + 15x = 0 5x(x + 3) = 0 therefore, x = 0 or x + 3 = 0 that is, x = 0 or x = -3
The question contains an algebraic expression but, since there is no equality sign, there is no equation to solve.
-3x6-25 is equal to -43
8x4=24 3x6=18 24-18 = 6 <--- Answer WRONG!!! 5/2 or 2.5
