To solve this problem, you can split the shape into a triangle and a parallelogram.
You can do this by imagining/drawing a line from point A to point C>
Now you can work out the area of triangle ACB
1/2 x b x h
1/2 x 5 x 3
= 7.5
Now work out the area of the parallelogram ACDE
b x h
5 x 3 = 15
Add the areas together and then you have the answer
7.5 + 15 = 22.5
2/3
16/24 and divide the greatest common factor (8)
Answer:
i guess its linear pair type questions
i have done like this
First find the area of the triangle shape:
Area of a triangle = 1/2 x base x height:
Area = 1/2 x 4 x 3 = 6 square cm.
For the volume multiply the area by the depth:
6 x 2 = 12 cubic cm
Answer:
x = ±3
Step-by-step explanation:
Step 1: Write equation
7x² = 63
Step 2: Solve for <em>x</em>
- Divide both sides by 7: x² = 9
- Square root both sides: x = ±3
Step 3: Check
<em>Plug in x to verify it's a solution.</em>
7(3)² = 63
7(9) = 63
63 = 63
7(-3)² = 63
7(9) = 63
63 = 63
