What is 3a squared?
Oh, what a happy little question! When we see "3a squared," we simply need to multiply 3 by a and then square the result. So, 3a squared is the same as 3 times a times a, which simplifies to 3a^2. Just like painting a beautiful landscape, math can be a lovely adventure of discovery and creativity.
Is it possible to make an expression which is equivalent to twenty using only three three's and any math operation?
No. You need at least four.
How do you solve the system of equations 3x-2y -7?
To solve a system of equations like 3x-2y=-7, you typically need another equation to find a unique solution. If there is only one equation given, the system is underdetermined and has infinite solutions. However, if you have additional information or constraints, you can potentially narrow down the possible solutions. In this case, without another equation or constraint, the system is unsolvable as it is currently presented.
How do you factorise the quadratic equation 2y squared - 2y -24?
2y2 - 2y - 24 has the factors (2y + 6) and (y - 4) There is a formula, but I always use trial and error. The factors of the non-x element need to be such that they can be added to give the middle element. So when you get 24, then you need to be looking at 2,12 - 3,8 - 4,6 When both the second and third element are minus values then there is a plus and a minus in the factors.
Evaluate the expression 17P2?
To "evaluate" an expression, you need to know the value for the variables.
