You can find the roots with the quadratic equation (a = 1, b = 3, c = -5).
Answer its 0.118
(2x3)+(3x5)-(3x2)= 2x3=6 3x5=15 3x2=6 So..... 6x25-6= 6x25=150 150+6=156
3x5+4=19
2+3*5 = 2 + 15 = 17
3x5 + 4x8 does not have a solution because it is not an equation. Are you looking for it's derivative? That would be: 15x4 + 32x7 Did you want it's indefinite integral? ∫(3x5 + 4x8) dx = x6/2 + 4x9/9 + C Or did you actually mean "three times five plus four times eight"? If so, the answer is 47.
(p+3)5 or p(3x5) depending on what way you say it.
Multiplication is done before addition, so it will be done before the plus. The result is:35 + 3 x 5 = 50
3a + a = 4a Example: a = 5 (3x5) + 5 = 15 + 5 = 20 = 4 x 5
17 = (3x5) + 2 = 5 + 5 + 5 + 2 = 10 + 7
1080 = 2^3x3^3x5 200= 2^3x5^2 LCM (1080,200) = 2^3x3^3x5^2 = 1800
prime factorization of each: 2x3 , 3x5, 2x2x5 so LCM = 2x2x3x5 = 60
There are 15 cells in a 3x5 table, calculated by multiplying the number of rows (3) by the number of columns (5).
