What is lateral surface area of cube?
4a square
4a plus 1-a equals 19?
4a + 1 - a =19, rewrite your question, 4a + -a + 1 =19, 3a + 1 =19, subtract 1 from each side 3a = 18, divide by 3, a =6
How do you find the length of the square with a perimeter 64Cm?
Perimeter of a square is given by 4a where 'a' is the side of square. Just put 64 equals to 4a which gives a=16
What is the answer to 1-4a equals 21?
The answer ... usually called the "solution" ... is the number that 'a' must bein order for the statement to be true. There's only one such number.You said that [ 1 - 4a = 21 ].I would begin by adding ' 4a ' to each side of the equation:1 = 21 + 4aNow subtract 21 from each side:-20 = 4aFinally, divide each side by 4 :-5 = a
What is the answer for the area of a circle whose radius is 2?
A=TTr2A=3.14 x 22A=3.14 x 4A=12.56Hope this helps

Perimeter of circle?
4a (where a is such a side)
What is a in problem 58 equals 4a -2?
58=4a-2 +2 +2 60=4a --- ---- 4 4 a=15 Remember the idea is to get a by itself, so you first add the 2 to each side ( because you have a negative 2) and then divide by 4 on each side to get a=15

What does a equals if 4a plus 24 equals 72?
If 4a+24=72 then you start out by subtracting 24 from both sides because what you do to one side of the equation you must do to the other. That means that 4a+24-24=72-24. So 4a=48. Now you divide both sides by 4 and you get a=12.
3a 4b equals 7a 4b?
Clearly, there are some signs missing. So let's try the four possibilities for the second terms: 1. + and + 3a + 4b = 7a + 4b Subtract 4b from each side: 3a = 7a Subtract 3a from each side: 0 = 4a Answer : a = 0, b indeterminate (ie can have any vaue). 2. + and - 3a + 4b = 7a - 4b Subtract 4b from each side: 3a = 7a - 8b Subtract 7a from each side: -4a = -8b or 4a = 8b Answer: a = 2b 3. - and - 3a - 4b = 7a - 4b Add 4b to each side: 3a = 7a Subtract 3a from each side: 0 = 4a Answer : a = 0, b indeterminate (ie can have any vaue). 4. - and + 3a - 4b = 7a + 4b Add 4b to each side: 3a = 7a + 8b Subtract 7a from each side: -4a = 8b or 4a = -8b Answer: a = -2b Can't do better than that with the information available.
What is 4a times 4a?
(4a)2 or 16a2
What is the additive inverse of -4a?
What is the additive inverse of -4a?
The vertex of this parabola is at 2 -4 When the y-value is -3 the x-value is -3 What is the coefficient of the squared term in the parabola's equation?
The general equation of a parabola is y = ax2 + bx + c.The vertex of a parabola is (-b/2a, c - b2/4a). In our case the vertex is (2, -4). So we have,-b/2a = 2, so that b = -4a, andc - b2/4a = -4 (substitute -4a for b)c - (-4a)2/4a = -4c = 16a2/4a = -4 (simplify)c - 4a = -4 (solve for c)c = 4a - 4By substituting -4a for b, and 4a - 4 for c, the equation becomes,y = ax2 + bx + cy = ax2 + (-4a)x + 4a - 4Since it is given that when x = -3, y = -3, we substitute them into the new equation and solve it for a. So we have,y = ax2 + (-4a)x + 4a - 4-3 = a(-3)2 + (-4a)(-3) + 4a - 4-3 = 9a + 12a + 4a - 4 (add 4 to both side, and add alike terms on the right-hand side)1 = 25a (divide by 25 to both sides)1/25 = a (this is the required answer)If you want to find the equation of the parabola, just substitute 1/25 for a, such as:y = ax2 + (-4a)x + 4a - 4y = (1/25)x2 + [-4(1/25)]x + 4(1/25) - 4y = (1/25)x2 -4/25x + 4/25 - 4y = (1/25)x2 -4/25x + 96/25
