Weegy: 6 x 3 + 10 ? 2 = 18+5 = 23
User: simplify: 6(y + 7)
Weegy: 42y is the answer
User: Multiply: (5xy^4) (2x^2y)
Weegy: Do you have more to the equation?
User: solve for x: -4x + 7 = 35
Weegy: The answer is x=-6,2. [ x^(2)-12=-4x
Since -4x contains the variable to solve for, move it to the left-hand side of the equation by adding 4x to both sides.
x^(2)-12+4x=0
Reorder the polynomial x^(2)-12+4x alphabetically from left to right, starting with the highest order term.
x^(2)+4x-12=0
In this problem 6*-2=-12 and 6-2=4, so insert 6 as the right hand term of one factor and -2 as the right-hand term of the other factor.
(x+6)(x-2)=0
Set each of the factors of the left-hand side of the equation equal to 0.
x+6=0_x-2=0
Since 6 does not contain the variable to solve for, move it to the right-hand side of the equation by subtracting 6 from both sides.
x=-6_x-2=0
Set each of the factors of the left-hand side of the equation equal to 0.
x=-6_x-2=0
Since -2 does not contain the variable to solve for, move it to the right-hand side of the equation by adding 2 to both sides.
x=-6_x=2
The complete solution is the set of the individual solutions.
x=-6,2 ]
User: solve for x: 4(x - 3) = 5(2x + 3)
Weegy: 2x - 6 + 5x = 10x + 30 combine like terms
7x - 6 = 10x + 30 subtract 7x and 30 both sides
-36 = 3x divide both sides by 3
-12 = x
Checking :
[ 2(x-3)+5x=5(2x+6)
2((-12)-3)+5(-12)=5(2(-12)+6)
2(-15) + 5(-12) = 5(-24+6)
-30 - 60 = 5(-18)
-90 = -90 - - - > true
therefore, x = -12

User: degree of the polynomial
Weegy: An example of a polynomial is 2x5 ? 5x3 ? 10x + 9.
User: given the polynomial x^5 + x^3 - 5x^9 + 6x^2. what is the degree of the polynomial ?
User: evaluate; x^2 + 13x + 15 when x=
User: x^0 is equal to o
Weegy: The answer is zero. The property is ...

4(x - 3) = 5(2x + 3);
4x - 12 = 10x + 15;
4x - 10x = 15 + 12;

x^0 is NOT equal to 0.
Anything that is raised to 0 is always equal to 1.
