What is the polynomial of 14x2-39x-35?
It is a quadratic expression and when factored it is: (7x+5)(2x-7)
What are four consecutive odd numbers that add up to 160?
Since every other number is an odd (starting from 1), we automatically could say x, x + 2, x + 4, x - 2, are the variables. Adding these together and setting it to 160 yields a linear equation:x - 2 + x + x + 2 + x + 4 = 4x + 4 = 1604(x + 1) = 160x + 1 = 40x = 39Now plugging into the variables, we have:x - 2 = 39 - 2 = 37x = 39x + 2 = 39 + 2 = 41x + 4 = 39 + 4 = 43Therefore, {37, 39, 41, 43} is the answer.
Why is .9 bar equal to 1?
1 over 3 is equal to .33333333.... So, 3 over 3 must be equal to .999999999... However, 3 over 3 is also equal to 1. So, this is proof that .99999999999999999.... is equivalent to 1.That is a pretty easy way to think about it. Just multiply each digit by 3, which is the same as multiplying 1/3 by 3. To convert any repeating decimal to fraction, follow these steps: Let x = the decimal. So for example x = 0.3333....Now multiply both sides by a power of ten, equal to the number of digits that repeat. So for example there is one digit which repeats (the 3), so multiply by 10¹ which is 10. So we have 10x = 3.3333.... So now we can subtract the original equation {x = 0.3333....} from the new equation. Remember the 3's repeat forever, so every one will cancel out all the way to the end:10x - x = (3.3333....) - (0.3333....) = 39x = 3 ; solve for x = 3/9 which simplifies to 1/3.Now do x= 0.9999.....10x = 9.9999.....10x - x = (9.9999....) - (0.9999....) = 99x = 9, x = 9/9 = 1.
Which expression is equivalent to 54 plus 39x-60?
39x-6
Factorise 14x squared minus 39x minus 35?
14x2 - 39x - 35 = (7x + 5)(2x - 7)
What is -90 - 39x plus 3x squared factored?
3x2-39x-90 = (3x+6)(x-15) when factored
What is 2x plus 39x equals?
41x
What value of N will make 7x-39x-17 true?
The given terms of the expression can be simplified to -32x-17 and no values of x can be found because it is not an equation.
14x2 - 39x - 35?
(2x - 7)(7x + 5)
Solve 2x 39x?
2x - 3= 9 x=
How do you solve 2-39x-50 equals 4 plus x?
2 - 39x - 50 = 4 + x -39x - 48 = 4 + x Add 39 x to both sides: -48 = 4 + 40x Subtract 4 from both sides: -52 = 40x Divide both sides by 40: x = -1.3
How do you solve X-2x equals 3x-43x plus 1?
For x-2x= 3x-43x+1 x-2x= -x and 3x-43x+1 = -40x+1 so -x= -40x+1 subtract -x from both sides 0= -39x +1 -1 = -39x so 1=39x so x=1/39
How do you factor 35x2-39x plus 10?
(7x - 5)(5x - 2)
3x - 6y equals 30 y equals -6x plus 34?
3x-6y=30 y=34-6x substitute the the value for y from the second equation into the first equation. 3x-6(34-6x)=30 3x-204+36x=30 39x-204=30 39x=234 x=234/39 x=6 Substitute this value of x into equation 2. y=34-6(6) y=34-36 y=-2
What is the answer for 42x-3y-35y-3x in distributive property form?
-38y - 39x (Is that what you were asking for?)
