You can write real numbers like this as:

-8

(-8)

-2*3

-2^(3)

I suppose you could also write in into standard form: 8

John is painting a picture.He has green, red, yellow, purple, orange and blue paint. He wants to use four different colors on th

devlian [24]

Answer:

I'm gonna say maybe 10..... yah 10

here's why

Answer:

In can pick in 10 ways.

Solution:

John has green, red, yellow, purple, orange, and blue paint = total 6 colours

he wants to have 4 different colours in the painting.

But in those 4 colors green is must, it should always be there.

So except green we have total 5 colours (red, yellow, purple, orange, and blue) from which we can pick any 3 colors(as green will be one in four colours).

Then we can choose 3 colours from 5 colours in x ways.

x ways = = \left(\frac{5 !}{3 !(5-3) !}\right)=(3!(5−3)!5!)

=\left(\frac{5 !}{3 ! \times 2 !}\right)=(3!×2!5!)

=\frac{5 \times 4 \times 3 !}{3 ! \times 2 !}=3!×2!5×4×3!

=\frac{5 \times 4}{2}=25×4

=\frac{20}{2} = 10=220=10

Effectus [21]

Answer:

1. -8x² - 16x - 6 a = -8, b = -16, c = -6

1. 4x² - 1 a = 4, b = 0, c = -1

Step-by-step explanation:

use the 'foil' method:

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

F: -8x² O: -12x I: -4x L: -6

-8x² - 16x - 6

(2x + 1)(2x - 1)

F: 4x² O: -2x I: 2x L: -1

4x² - 1

If 5x+ 3 = 10x– 17, what is the value of x? A. 1 B. 2 C. 3 D. 4 E. 5

Sedbober [7]

Answer:

Step-by-step explanation:

First, we will move the variable to the left-hand side and change its sign: 5x + 3 - 10x = -17

Next, we need to collect like terms: -5x = -20

Finally, we will divide both sides of the equation by -5 to give us the answer of x = 4.

Area of the figure = 112 in²

Solution:

The given figure is splitted into two shapes.

One shape is square.

Each side of square are equal.

Side = 10 inch

Area of the square = side × side

= 10 × 10

= 100

Area of the square = 100 in²

The other shape is triangle.

Base of the triangle = 10 in – 6 in = 4 inch

Height of the triangle = 16 in – 10 in = 6 inch

Area of the triangle = $\frac{1}{2}\times \text{base}\times \text{height }$

$$=\frac{1}{2}\times4\times6$

= 12

Area of the triangle = 12 in²

Area of the figure = Area of the square + Area of the triangle

= 100 in² + 12 in²

Area of the figure = 112 in²

Therefore, area of the given figure is 112 in².
