Suppose that you have a stack of pennies. If you want to know without counting whether there is an odd or even number of pennies, then you have to split them into two parts, for example,  placing one coin left and one coin  right.

If the number of pennies is even, then no coins will left, if the number is odd, then one coin will be extra.

The power 0 only affects the x. x^0 = 1

-2 * 1 = -2

25

Here everything inside the brackets is affected by the 0.

(11abx)^0 = 1 There is nothing left over.

26

(xy)^0 = 1

(pq)^0 = 1

1 - 1 = 0

Does anyone know the answer?
azamat

Answer:

1=163 degrees

2=×=10 degrees

3=×=3

Step-by-step explanation:

54x+1+9x-10=180 we are using this expression because alternate angles add up to 180 degrees

54x+9x+1-10=180

63x-9=180

63×=180+9

63×=189

63×÷63×=189÷63×

X=3

Angle in bold print is (54x+1)

54×3=162

162+1=163 degrees

No.2 Find x

7x+35+x+65 =180

7x+x+35×65=180

8x+100=180

8x=180-100

8x=80

8x÷8x=80÷8

X=10 degrees

No.3 Find x

54x+1+9x-10=180

54x+9x+1-10=180

63x-9=180

63x=180+9

63x=189

63x÷63x=189÷63

X=3

Evaluate 4(3h + 7)<br> ————— for h = -2<br> 4 +h
Juliette [100K]

If i understood the question right, you're trying to find the value when h = -2. If that's true so here is how it's done:

4(3h + 7)\\4(3(-2) + 7)\\4(-6+7)\\4(1)\\=4
