Photo math helps :) I’ve been using it for this problems
Answer:
3t +15
Step-by-step explanation: first multiply the 3 to the T but you can't so you leave it 3t then 3 x 5 = 15 your sum is 3t +15
There are two ways to find the answer. You could use cross-product or common denominator. To get the common denominator, change the denominators to 12 by multiplying both sides of 2/3 by 4. This gives you 8/12. 8/12 is less than 11/12.
Cross-product is easier and more time saving than changing into common denominators, though. In order to do this, set up your fractions vertically. Multiply the numerator of the first by the denominator of the second. Place the product above the second fraction. Then, multiply the numerator of the second fraction by the denominator of the first. Next, place the product above the first fraction. Then compare the two products. Whichever fraction has the greater number on top is the greater fraction. To do this, 11x3 is 33. Write that over 2/3. 2x12 is 24. Write that over 11/12. Since 33 is greater than 24, 2/3 is greater.
The final answer is: 11/12<2/3.
Answer:
The area of the given polygon is:
Step-by-step explanation:
To find the area of the polygon in the picture, you can divide the polygon in three rectangles: a 3 cm by 14 cm, a 5 cm by 14 cm rectangle, and the last rectangle must have a base of 12 cm (20 cm - 3 cm - 5 cm), and a height of 10 cm (14 cm - 4 cm). We can calculate the area of the rectangles with the formula below:
- Area of a rectangle = Base * height
Now, we're gonna replace the measurements in the formula.
<em>First rectangle:</em>
- Area of a rectangle = 3 cm * 14 cm
- <u>Area of a rectangle = 42 cm^2</u>
<em>Second rectangle:</em>
- Area of a rectangle = 5 cm * 14 cm
- <u>Area of a rectangle = 70 cm^2</u>
<em>Third rectangle:</em>
- Area of a rectangle = 12 cm * 10 cm
- <u>Area of a rectangle = 120 cm^2</u>
By last, we must add the area of the rectangles:
- Area of the polygon = 42 cm^2 + 70 cm^2 + 120 cm^2
- <u>Area of the polygon = 232 cm^2</u>
As you can see, <em><u>the area of the polygon in the picture is 232 cm^2</u></em>.
I don’t know if you want both but I’m going to give you both.
(0,2) and (4,3)
