45 equals 7x - 4 solve?
45+4 = 49 49/7=7 7*7=49-4=45 so x=7
How do you factor the polynomial 7x plus 49?
Factoring involves 'factoring out' the common numbers for each term. In a simple general form, a + ab = a(1+b). It's like "undistributing" factors: instead of multiplying both terms by a number, you essentially divide both terms by a number. In (7x + 49), both terms - 7x and 49 - have 7 as a factor. So, it can also be written: 7x + 49 = 7(x+7)
The product of what number and 7 is less than 49?
your expression is this... 7x < 49 x < 7 so any number below 7 can be your answer
What is 7x minus x?
6x
What is 6x plus x?
6x+x=7x
Resolve -7x equals -49?
42
How do you factor 7x plus 49?
Factoring requires you to reduce as much as possible. To factor 7x + 49, you remove the common factor of 7x and 49, which is 7, and multiply (7x + 49)/7 (which is x + 7) by 7, without actually simplifying. 7x + 49 = 7(x + 7) Then, if possible, do the same thing until it cannot be further factored.
Find a number such that 5 less than 7 times the number is 44?
If 7x - 5 = 44 Then 7x = 44 + 5 = 49 x = 49/7 Therefore, x = 7
How do you factor 7X-49?

Find a number whose product with 8 is the same as its sum with 49?
Call your number "x", write an equation, and solve it: 8x = x + 49 7x = 49 x = 7
What is the product of x and 7 in algebraic form?
Watch closely:It's 7x
What are the exact solutions of x2 4 - 7x?
Do you mean the following? x2 = 4 - 7x If so, then: x2 + 7x = 4 x2 + 7x + 49/4 = 4 + 49/4 (x + 7/2)2 = 65/4 x + 7/2 = ±√65 / 2 x = (-7 ± √65) / 2 So x is equal to (-7 - √65) / 2 and (-7 + √65) / 2
How would you factor x3 plus 343?
(x + 7)(x2 - 7x + 49)
How would you factor x3 minus 343?
(x - 7)(x2 + 7x + 49)
What is the factorization of this trinomial 2x2 plus 21x plus 49?
2x2 + 21x + 49 = 2x2 +14x +7x + 49 = 2x(x + 7) + 7(x + 7) = (2x + 7)(x + 7)
What is the factorization of 2 times x squared plus 21x plus 49?
2x2 + 21x + 49= 2x2 + 14x + 7x + 49= 2x(x + 7) + 7(x + 7)= (x + 7)(2x + 7)
Solve by substitution x plus 5y equal 10 and 7x minus 14y equal 49?
set it up as x+5y=10 and 7x-14y=49 on top of each other and then multiply x+5y=10 by -7. That gives you -7x-35y=-70. cross out the X's and add the Y's. -21y=21 divide and get -1=y then sub. for x and solve. X=15 and X=5
