How do you solve 2x 15x 7?
210
What is the answer to 4(2x-5)?
It is: 8x-20
The product of three consecutive whole numbers is 210 what is the?
(x)(x + 1)(x + 2) = 210 (x^2 + x)(x + 2) = 210 x^3 + 2x^2 + x^2 + 2x = 210 x^3 + 3x^2 + 2x = 210 x^3 + 3x^2 + 2x - 210 = 0 Let's try 5, as a factor of 210. 5] 1 3 2 -210 5 40 -210 ---- 8 42 0 remainder, so 5 is a root. Since 5 is a root of the equation, let say that 5 is the first number. So, the second number is 6, and the third number is 7. Check: 5 x 6 x 7 = 210
The supplement of an angle added to the complement of the angle gives 210 degrees What is the measure of the angle?
Suppose the angle is x degrees. Then its supplement is 180 - x and complement is 90 - x So 180 - x + 90 - x = 210 ie 270 - 2x = 210 so 2x = 60 or x = 30
Are 2 to the power of x and 2x the same?
No. 2x means 2 times x. For example, 210 = 1024, while 2 x 10 = 20.
Which of the following is the equation of a line that passes through the points (06) and (210)?
Answer this question…y = 2x + 6
What is the length of a rectangle that has a perimeter of 210 given that the width is exactly two thirds of the length?
210 = 2x + 2(2/3*x) = 10/3*x x = 63
Find the measure of an angle that is 30 degrees more than its supplement?
Suppose the measure of the angle is x then its supplement is 180 - x x = 180 - x + 30 = 210 - x 2x = 210 => x = 105 degrees (supplementary angle = 75)
What is -2x plus 2x?
It is 2x+(-2x) = 0
Why is 2x cubed different from 2x times 2x times 2x?
2X * 2X * 2X = 8X^3 2X^3 is saying 2*( X * X * X) = 2X^3
How do you do 2x times 2x?
2x * 2x (2*2=4) therefore, 2x*2x equals 4x2.
What is the solution to 10x-7y equals -1 and -2x-7y equals -25?
10x-7y=-110x+1=7y-2x -10x-1=-25-12x-1=-25-12x=-24x=-24/-12x=210(2)-7y=-120-7y=-121=7y21/7=yy=3
