Answer:
2x^2-4x-16
Step-by-step explanation:
2(x^2-2x-8)=2x^2-4x-16
Answer:
b 43.5 cm^2
Step-by-step explanation:
The area of a trapezoid is found by using the formula
A = 1/2 (b1+b2) h
where b1 and b2 are the lengths of the bases
A = 1/2(13 +16) *3
A = 1/2 (29)*3
A = 43.5 cm^2
Answer:
0.375
Step-by-step explanation:
Using proportions, it is found that the coordinates of point P are given as follows: (2,10).
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
The segment is partitioned by point P according to the ratio of 3:4, hence:

This proportion is applied for both coordinates, hence, for the x-coordinate:

x - 2 = 0
x = 2.
For the y-coordinate:

y - 4 = 6
y = 10.
Hence the coordinates are (2,10).
