Answer:

So first we need to do 2*(-2) thats easy because anything times 2is 2x. So the first one is -2+-2 or -4. The next one is also easy because anything times 1 is x so it will be -2. Next we know that 2 minuses become positive so -1*-2 = 1*2 = 2. And same goes for the next one, they cancel out yielding 2*2 = 4

Anyone know the area?

Elina [12.6K]

Answer: The area of the triangle is: " 8.5 cm² " ;

or, write as: " 8 $\frac{1}{2}$ cm² " .
_______________________________________________________
Explanation:
_________________________________________________________
The formula {"equation"} for the area of a triangle is:

A = ( $\frac{1}{2}$ ) * b * h ;

in which: A = area;
b = base;
h = [perpendicular] height;
___________________________________
{also, can be written as: " A = (b * h) / 2 " .}.
______________________________________
Solve for the area, "A" ; by plugging in the known values shown in the figure (image attached):
______________________________________
base, "b" = 13 cm ;
[perpendicular] height, "h" = 5 cm ;
______________________________________
A = (b * h) / 2 ;

= (13 cm * 5 cm) / 2 ;

= [ (13 * 5) cm²] / 2 ;

= 65 cm² / 2 ;

A = " 8.5 cm² " ; or, write as: " 8 $\frac{1}{2}$ cm² " .

Firdavs [7]

Answer:

8 hours

Step-by-step explanation:

We can use a ratio to solve

12 hours x hours

---------- = ------------

93 dollars 62 dollars

Using cross products

12 * 62 = 93x

Divide each side by 93

12*62/93 = 93x/93

8 = x

Help me please !!!!!

Anuta_ua [19.1K]

You are correct!

90 would be the correct choice, here is why:

use the eqation: $20*30*15%

first times $20*30=600

now, 600 *15%= $90

therefore, your answer is 90 dollars
