The image contains two geometric objects, square and triangle
The square
The square has side equals to 12 cm
Find the area of the square
a = s × s
a = 12 × 12
a = 144 cm²
The triangle
The triangle has base equals to 12 cm, and the height equals to 17 - 12 = 5 cm
Find the area of the triangle
a = 1/2 × b × h
a = 1/2 × 12 × 5
a = 1/2 × 60
a = 30 cm²
Now add the area together
a = area of triangle + area of square
a = 144 + 30
a = 174
Answer:
The area is 174 cm²
1/6 is the only one that repeats forever. 0.16666666666etc.
Answer:
(3)(x+7)(x-1)
Step-by-step explanation:
3x^2+18x-21
Let's start by taking 3 out of the equation.
3(x^2+6x-7)
Now, when we factor, we need to find two numbers that add up to 6 and multiply to -7.
The numbers would be 7 and -1.
So the factored form of this would be:
(3)(x+7)(x-1)
186cm
You add all the sides up, so 42+42+51+51 which equals 186cm
