H = 1 + sin(3t)
When t = 5, H = 1 + sin(15) = 1 + 0.2588 = 1.26 metres, approx.
4{3x-2}2=36 12x-8=18 12x=26 x=2.16666... I hope I read that equation right. If not, just message me and I can fix it.
(x-2)(x+2)= x2+2x-2x-4= x2-4
2log4(7x) - 5 = 0 2log4(7x) = 5 log4(7x) = 5/2 7x = 45/2 =(41/2)5 = 25 = 32 x = 32/7
Complete the square, then find the value of x that would make the bracket zero ax^2 + bx + c = 0 line of symmetry is x = (-b/2a)
In a pedigree, a vertical line and a bracket connect _____.
To expand an equation you multiply the number outside the bracket with everything inside the bracket. ex. 3(x+3) becomes 3x+9
You can remove parenthesis or bracket by multiplying the number outside, with the number inside the bracket.
... which is 2x + 2 = x so x = -2
[a+b]2 = [a+b]*[a+b]= a*a + a*b + b*a + b*b= a2 + 2ab + b2
4{3x-2}2=36 12x-8=18 12x=26 x=2.16666... I hope I read that equation right. If not, just message me and I can fix it.
The answer is x = 9 and the workings and explanation are below for your information.3(3x + 1) = 4(2x + 3)First we need to multiply out the brackets. We will do this by multiplying each term inside the bracket with what is outside the bracket. So on the left side of the equation, for example, we will get:9x (because this is 3x * 3) + 3 (because this is 3 * 1).So when we multiply out both brackets we will get:9x + 3 = 8x + 12We now need to move all the "x's" to one side of the equation and all the constants (the numbers) to the other side. When we move anything from one side of an equation to the other side we have to change a positive to a negative and vice versa.So we will get:9x - 8x = -3 + 12Now we can simplify both sides to:x = 9.
Insufficient information to solve equation, however it can be simplified. Assuming it looks like this 2 (3y+6) The simplified version would be 6y+12
4[x+3]=4x+12 4x+12=4x+12 it's open.
3(4 - x) - 6(4 - 3x) = 3 Expand the brackets: 12 - 3x - 24 + 18x = 3 [note that -6*(-3x) gives +18x] Combine like terms: -12 + 15x = 3 Add 12 to both sides: 15x = 15 Divide both sides by 15: x = 1.
Pipe bracket.
5 (2x - 1) = 10Eliminate parentheses on the left side of the equation:10x - 5 = 10Add 5 to each side:10x = 15Divide each side by 10:x = 1.5
the [ and ] brackets are for if you need an equation like [(9+1)+5] so if you need parenthesis in another parenthesis that is what its for and so is { and }
