2a x -4?
6
2a x 2a?
The answer is 4a^2.
What is 2a x a?
2a2
What is x plus 2a?
x + 2a
If 24 equals 2a x 3 what is the value of a?
2a x 3 = 24= 6a = 24(divide both sides by 6)a = 4
What is the answer to 2a x 3b?
2a x 3b = 6ab
What is 2a plus 4 times 3?
2 + 4 = 6 x 3 = 18
The length of a rectangle is 2a. The width is 3a - 4. Find the area of the rectangle in terms of the variable x?
The area, in terms of a, is 2a*(3a-4) = 6a2-8a However, it is not possible to give its area in terms of x without knowing anything about x, such as how x relates to a.
What is the axis of symmetry formula?
-b/2a. i think.To show this, consider this equation:y = ax² + bx + cFactor out the a:y = a(x² + bx/a + c/a)Then, complete the squares to get:y = a(x² + bx/a + (b/(2a))² + c/a - (b/(2a))²)= a((x + (b/2a))² + c/a - (b/(2a))²)= a(x + (b/2a))² + c - b/(4a)By the vertex form:y = a(x - h)² + k where x = h is the axis of symmetry.So the general axis of symmetry for the quadratic equation is x = -b/(2a).
What is 2a x 3x?
Since you cannot multiply x by a, in the answer you get ax. 2a * 3x = 6ax
What is the value of 2 times A times by 2 times B times by 5 times A times B minus 4 if A-4 and B5?
A=-4 b=5 2a=-8 2b=10 5ab=-100 2a x 2b x 5ab= -8000
Solve each equation 2a-4 459-a check?
2a-8+4=45-5a 2a-4=45-5a 2a-4+4=45+4-5a 2a+5a=49-5a+5a 7a=49 / by 7 = A=7
