Answer:
Everything except the finding the midpoint
Step-by-step explanation:
If the question states the points of a shape, you can find the perimeter and the area of the polygon because you would know the dimensions and the lengths of each side, but in the options, it says the area of a rectangle, and it doesn't have to be a rectangle
You can find the equation of the circle, by finding the diameter of the circle and the radius. With the diameter, you would be able to find the centre of the circle and then you need to divide the diameter by two to get the radius.
For the midpoint, you use the midpoint formula. You just need to sub in the points into the formula and you would get the midpoint
When you are given two points on a graph (or worded problem), and it says that for every x number of km it uses y amount of gas and the question asks to find how much gas is needed in between these two points, you can do this. Find the distance between the two points and then use algebra to work out the amount of gas required
Answer:
It is a factor
Step-by-step explanation:
[x³ -7x² + 8x + 16] ÷ (x + 1)
[x³ + x² - 8x² - 8x + 16x + 16] ÷ (x + 1)
[x²(x + 1) - 8x(x + 1) + 16(x + 1)] ÷ (x + 1)
x² - 8x + 16 and tye remainder is 0.
So, yes (x + 1) is a factor
Convert to base 10
2×3² + 0×3¹ + 1×3^0 = 18 + 0 +1 = 19 base 10
so convert 19 to base 8
19 base 10 = 23 base 8
D is your answer
Answer is 10, all you have to do is add all the numbers together and multiply by how many number you added together, which is 10
