Answer:

x = 3

Step-by-step explanation:

AC and BD are going to be the same measure. We can make an equation and solve for x.

3x + 1 = 4x - 4

~Add 1 to both sides

3x = 4x - 3

~Subtract 4x to both sides

-x = -3

~Divide -1 to both sides

x = 3

Best of Luck!

A car was on sale for

Answer:

p - 0.05p

Step-by-step explanation:

The price of the car is p.

You must subtract from p the amount of 5% of p.

5% of p = 5% * p = 0.05p

5% of p is the same as 0.05p.

Now we subtract 0.05p from p.

p - 0.05p

Answer:

Circumference: 25.12

Step-by-step explanation:

Circumference = 2 $\pi r$ or $\pi d$ . ( r stands for radius and d for diameter) Since pi is 3.14, 8 times 3.14 is 25.12.

3.14

x 8

25.12

(If you mean area of the circle its 50.24, circumference times 2)

Completely factor the polynomial. 4x^2 20x 25

Sergeu [11.5K]

I use the railroad method so here's how I would solve it:
4 x 25 = 100
10 x 10 = 100, 10 + 10 = 20
(x +10/4)(x + 10/4)
(x + 5/2)(x + 5/2)
The answer should be: (2x + 5)(2x + 5)

It can be checked:
2x x 2x = 4x^2
2x x 5 = 10x
5 x 2x = 10x
5 x 5 = 25
4x^2 + 20x + 25

So yes, the answer would be (2x + 5)(2x + 5)
