Answer:

AB║CD

let a & b be length of parallel sides distance between them is h.

area of trapezium =

1/2 ah + 1/2 bh = 1/2 h ( a + b )

hope this answer helps you.....

What is the discriminant of the polynomial below 4x^2-20x +25

svetlana [45]

Answer:

The discriminant D=0

Step-by-step explanation:

For the duadratic polynomial $ax^2+bx+c$ the discriminant is

$D=b^2-4ac.$

In your case, for the polynomial $4x^2-20x+25,$

$a=4;$
$b=-20;$
$c=25;$
$D=(-20)^2-4\cdot 4\cdot 25=400-400=0.$

8. To calculate 159 - 73, a student writes the follow-

Evgen [1.6K]

The question is an illustration of solving equations using estimates.

The student's strategy makes sense because he uses estimation to solve the given equation

The correct sequence of equation is as follows:

$\mathbf{159 - 73}$

$\mathbf{159 - 73 =160 - 70- 1 - 3}$

$\mathbf{159 - 73 =90- 4}$

$\mathbf{159 - 73 =86}$

We have:

$\mathbf{159 - 73}$

Add 0 to the equation

$\mathbf{159 - 73 =159 + 0- 73}$

Express 0 as 1 - 1

$\mathbf{159 - 73 =159 + 1 - 1- 73}$

$\mathbf{159 - 73 =160 - 1- 73}$

Add another 0

$\mathbf{159 - 73 =160 - 1- 73 + 0}$

Express 0 as 3 - 3

$\mathbf{159 - 73 =160 - 1- 73 + 3 - 3}$

$\mathbf{159 - 73 =160 - 1- 70 - 3}$

Rewrite as:

$\mathbf{159 - 73 =160 - 70- 1 - 3}$

Solve

$\mathbf{159 - 73 =90- 4}$

$\mathbf{159 - 73 =86}$

Help please i dont get it ( i dont pay attention in class...)

ss7ja [257]

Answer:

Okay, I won't give the answers... HOWEVER, I will show you how to get them yourself! :>

Step-by-step explanation:

A triangles area is essentially half of a square. In my math class, we would multiply the main base, and the height and then proceed to break it in half. For example;

TRIANGLE ONE-- 16 x 16 =__ then cut your answer in half
