FranAh, what a lovely question! When you have 2a multiplied by a, you simply add the exponents of a together. So, 2a x a equals 2a^2. Just imagine those a's dancing together, creating a beautiful square of a's on your canvas. Happy multiplying, my friend!
The expression 2a x a can be simplified by multiplying the coefficients and the variables separately. Multiplying 2a by a gives 2a^2, where the coefficient 2 is multiplied by the coefficient 1 (implied) to give 2, and the variable a is multiplied by a to give a^2. Therefore, 2a x a simplifies to 2a^2.
Well, darling, 2a x a is simply 2a^2. It's like combining two a's and multiplying them together. So, there you have it, sweetie, 2a x a equals 2a squared.

What is 2a x 3x?
Since you cannot multiply x by a, in the answer you get ax. 2a * 3x = 6ax
What is the area of an equilateral triangle of side 2a?
The height of an equilateral triangle is √3/2 x side_length. So for an equilateral triangle of side length 2a, the area is: area = 1/2 x base x height 1/2 x (2a) x (√3/2 x 2a) = √3 a2
What is the geometric mean of a and 4a?

Where did the quadratic formula come from?
The quadratic formula originated from the concept of completing the square. let's take ax2 + bx + c = 0. To complete the square, solve for x. Subtract c. ax2 + bx = -c. Then divide by a [notice- if there is no a value, then a=1]. x2 + bx/a = -c/a. Add (b/2a)2 to both sides. x2 + bx/a + b2/4a2 = -c/a + b2/4a2 Factor/Reformat. (x + b/2a)2 = (b2-4ac) / 4a2 (x + b/2a)2 = [(b2-4ac) / 2a]2 Square-root both sides. x + b/2a = ± √(b2-4ac) / 2a Subtract b/2a. x = -b/2a ± √(b2-4ac) / 2a Combine terms. x = [-b ± √(b2-4ac)] / 2a
What is x plus 2a?
x + 2a
What is the answer to 2a x 3b?
2a x 3b = 6ab
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 2a minus a?
2a - a = a
What is 2 to the power of 0 why?
20 = 1Consider what is the value of 2a ÷ 2a? Any number divided by itself is 1. Thus:2a ÷ 2a = 1The law of indices says that when dividing, they are subtracted, for example:25 ÷ 22 = (2 x 2 x 2 x 2 x 2) ÷ (2 x 2) = 2 x 2 x 2 = 23 = 25-2So 2a ÷ 2a is (also):2a ÷ 2a = 2a-a = 20Since any number subtracted from itself is 0 (= a - a). This must have the same value as before, thus:20 = 1The 2 above can be replaced by any number x which means that any number to the power 0 is 1:x0 = 1
What is the area of an equilateral triangle of side 2a?
The height of an equilateral triangle is √3/2 x side_length. So for an equilateral triangle of side length 2a, the area is: area = 1/2 x base x height 1/2 x (2a) x (√3/2 x 2a) = √3 a2
What is the geometric mean of a and 4a?
x2=(4a)(a) x=√4a2 x=2a The geometric mean of a and 4a is 2a
How do you put this sum 52 x 2a?
52 times 2a = 104a
What is the mathimatical equation a x a simplified to?
The answer is 2a because of the two a's equal 2a
If f of x equals 3x - 10 then what is f of 2a?
if f(x) = 3x - 10, then whatever is put (substituted) for x in the "f(x)" bit is substituted for x in the "3x - 10" bit. Thus f(2a) = 3(2a) - 10 = 6a - 10.
