-3x plus 6 plus 15x equals 11x plus 8?
-3x + 6 + 15x =11x + 8 ie -3x + 15x - 11x = 8 - 6 ie x = 2
-9y - 15x -3?
-9y-15x ---- -3
X2-15x plus 56 equals 0 in factored form?
x2-15x+56 = 0 (x-8)(x-7) = 0 Therefore: x = 8 or x = 7 To ensure that your answer is correct multiply out the brackets and you should go back to the original quadratic equation.
What is the correct classification of x2 15x?
The correct classification of x2 15x is a monomial.
What is 3x 5x-5?
15x because 5 cant go into 15x look at it like this 5 is a bird and 15x is a bee birds and bees are not the same so you cant add them the answer is 15x-5 good luck
WHAT IS -15X plus 12-8?
hmm it would be -15x+12-8 so on this problem you just simplfy it would be -15x+4
-3x plus 6 plus 15x equals 11x plus 8?
-3x + 6 + 15x =11x + 8 ie -3x + 15x - 11x = 8 - 6 ie x = 2
Solve the equation 15x minus 12 equals 3x plus 8?
15x minus 8=minus 180 3x+8=24
'8 - 6x - 9x - 7'?
-15x + 1
15x - 8 - 3x equals 16?
Set up the equation and solve: 15x - 8 - 3x = 16 (next add 8 to each side) 15x - 3x - 16 + 8 (next simplify) 12x = 24 (next divide both side by 12 to solve for x) x = 2
What is the factorization of the polynomial of x2 - 15x - 56?
This will only give a rational answer when it's +56. Then you're looking for two numbers that add to 15 and multiply to 56. That's 7 and 8. If it's -15x, the answer is (x - 8)(x - 7) If it's +15x, the answer is (x + 8)(x + 7)
8 percent of 15.00 is what?

How do you solve -15X equals -5 times 3X plus 2?
-15x=-5*3x+2 -15x=-15x+2 +15x +15x ----------------- 0=2
What is factor of x2 plus 15x 56?
(x + 7)(x + 8)
What is the volume of a cuboid when its height is in the ratio of 15 to 8 to its width and has a length of 22 cm with a surface area of 2506 square cm showing work?
Suppose the height is 15x cm. Then the width is 8x cm. Then the surface area is 2*(15x*8x + 8x*22 + 22*15x) cm2 Therefore 2*(15x*8x + 8x*22 + 22*15x) = 2506 or 15x*8x + 8x*22 + 22*15x = 1253 120x2 + 506x - 1253 = 0 so that x = -529/30 or 13/4 But x cannot be negative so x = 1.75. Therefore, volume = (15*1.75)*(8*1.75)*22 = 8085 cm3
What is 35x - 15x?
