What is the perimeter of quadrilateral ABCD?

Mathematics
1 answer:
Bogdan [553]3 years ago
5 0

Answer:

I believe it is 18 + the square root of 26.

Step-by-step explanation:

The slope of line BC should be 5/1 because it goes up 5 times and to the right once. If you square root 26 you get 5.09.

Factorize by splitting the middle term 6x-11x+4​
Gennadij [26K]

Answer: (2x - 1)(3x - 4)

(split -11x as -8x and -3x)

Step-by-step explanation:

I am assuming that it is actually 6x^2 - 11x + 4

To find out how to split the middle term: The two numbers should multiply to a*c (6*4 = 24) and add to b (-11)

-8, -3 works

(6x^2 - 8x) + (-3x + 4)

2x(3x - 4) + -1(3x - 4)

(2x - 1)(3x - 4)
