Answer:

Step-by-step explanation:

2*37 equals 74

(2*3)*7 is a different case. You first have to do what is inside the parentheses. 2*3 is 6. 6*7 equals 42. You wouldn't distribute in this case, because of the multiplication position and PEMDAS.

Hope this helps!

Answer:

Step-by-step explanation:

Given

$\frac{1}{3}$ x - 8 = - 12 ( multiply through by 3 to clear the fraction )

x - 24 = - 36 ( add 24 to both sides )

x = - 12 → A

Terri is rewriting 7 to the 13th power in expanded form. How many factors should she use in her expression?

Pachacha [2.7K]

13

Because the exponent is really just how many factors you have.
For example 2 to the power 5 would have 5 factors in expanded form.

Jia is tiling a floor. The floor is a square with side

NNADVOKAT [17]

Answer:

36 tiles

Step-by-step explanation:

First, find area of the square floor knowing the formula as;

Area= $s^{2}$

where s= side of a square.

If one side of the floor is 12 feet, then Area= $12^{2} = 144ft^{2}$

Next, find the area of each tile using the same formula and given s=2 feet;

Area(tile) = $2^{2} = 4ft^{2}$

To find the number of tiles needed to cover entire floor, divide area of the floor by area of one tile; 144 / 4 = 36 tiles

Evaluate (if possible) the six trigonometric functions of the real number. (If not possible, enter IMPOSSIBLE.)

kotegsom [21]

$\sin(t) = \frac{1}{2} 
\\
\\ \cos(t) = - \frac{ \sqrt{3} }{2} 
\\
\\ \tan(t) = \frac{\sin(t)}{\cos(t)}= - \frac{1}{ \sqrt{3} } 
\\
\\ \csc(t) = \frac{1}{\sin(t)}= 2 
\\
\\ \sec(t) =\frac{1}{\cos(t)}=- \frac{2}{ \sqrt{3}} 
\\
\\ \cot(t) = \frac{1}{\tan(t)}=- \sqrt{3}$
