Expand the brackets .You will have to multiply it.
6x2 +10x-3x-5
Final answer will be
6x2+7x-5
x2 means (x square)
Sycamore=15.6 recurring
Oak=14.75
Maple=15.75
Birch=15.72
Therefore, A and B are true
Problem 1: Plug in the given value into the function and evaluate.
Problem 2: Solve the equation for y.
add 7x to both sides to move it to the right side of the equation.
Divide both sides of the equation by 2 to get a single y variable on the left hand side.
Simplify the terms to get the the equation into slope-intercept form.
The slope of the line is 
I'm a unsure what Problem 3 is asking for sorry I hope the rest is helpful.
The centre is the median of the data, so the middle number. IT can also be the mean which is the average.
The spread tells you about the rang of the data.
The shape describes the different types of graphs you get if you graph the data so it could be symmetric or skewed etc. The different shapes tell you different things. For example, a skewed graph might tell you people prefer a certain option.
