Multiply x plus 3 x plus 4 equals?
(x+3)(x+4)=x2+7x+12
What is order pair for 7x-3y equals 21?
7x-3y=21 Think of it this way. Block 3y or multiply 3(0)=0. Then you get: 7x=21 X=3 In vice versa, block 7x or multiply 7(0)=0 and look at: 3y=21 Y=7 So an ordered pair is (x,y) Thus, you get (3,7)
When you multiply a number by 7 and add 8 to the answer it makes 50 what is the number?
Not too sure about your question but let the number be x:- If: 7x+8 = 50 then x works out as 6 But if: 7x = 42+8 then x works out as 7 and 1/7
How do you factorise 7x-x squared?
7x-x2 = x(7-x)
What is the answer for -7x-2?
Assume you mean -7x-2=0 solve for x -7x-2=0 -7x=2 -x=2/7 X=-2/7
How do you do this problem 3-2 x 7X?
its pretty easy: 3-2 = 1 so if u multiply 1 x 7x, it equals 7x
Multiply the following x 3 x 4?
The answer is A. x to the second power + 7x + 12. This answer is by Blueguy44
Multiply x plus 3 x plus 4 equals?
(x+3)(x+4)=x2+7x+12
What is the answer to 7x 7x squared?
7x^3. That is 7x cubed.... or 7x*7x*7x (where * means multiply). You should get 343x

Multiply the following x plus 3 x plus 4 equals?
(x+3)(x+4) = x2+7x+12
How do you fast multiply a number by 7?
out = in+in; /* 2x */ out += out; /* 4x */ out += out; /* 8x */ out -= in; /* 7x */ or out = (in<<3) - in; /* 8x - x */
How do you rearrange v divided by 7x equals w divided y to make x the subject?
v/7x = w/y Multiply both sides of the equation by x, to get: v/7 = xw/y Multiply both sides of this equation by y/w, to get: vy/7w = x .
How do you solve 7x-2 equals x plus 4?
7x-4=x+2 7x=x+2+4 7x=x+6 7x-x=6 6x=6 X=1
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.
What is x squared-7x equals 8 factored?
x2 - 7x = 8 x2 - 7x - 8 = 0Now find two numbers that multiply to equal -8, and add to equal -7.(1) * (-8) = -8(1) + (-8) = -7(x+1)(x-8) = 0 This is the factored form of x2 - 7x = 8You can then solve the equation if necessary, and get:x = -1 or x = +8
