You have to use factoring by grouping.. multiply by 8 and 15 and what factors add to -14.
The factors are 6 and -20
(2x-5)(4x+3)
Answer:42 + 59 is 101
Step-by-step explanation: so draw the line for the number line and mark it by tens by going 10 20 so on and so on then do 4 of the ten hops and and 2 tiny hops then get a diffrent color pencil and do the number 59 in jumps
The answer to the question is 6 yards and 2 feet
To get the perimeter of the trapezoid, we will add the lengths of the 4 sides together.
So, first we will need to get the length of each side.
Base of trapezoid = 8 - 2 = 4 unitsThe upper edge of the trapezoid = 6 - 4 = 2 unitsNow, for the two side edges, we can note that
they are both equal. So, we need to get only one length (as the other would be the same). I will get the length of the left side.
Coordinates of the start point are (2,4) which represent (x1,y1)
Coordinates of the end point are (4,9) which represent (x2,y2)
To get the distance between the two points, we will use the rule attached in the image below as follows:
distance = sqrt ((4-2)^2+(9-4)^2)
distance = √29
Therefore, each of the side edges equal √29 unitsFrom the above, we can now easily get the perimeter as follows:perimeter = 6 + 2 + √29 + √29
perimeter = 8 + 2√29 units
Based on the above calculations, the best choice would be:D. 8 + 2√29 units
