Answer:
168 mm²
Step-by-step explanation:
Let A be the area of this shape
the kite is made of two triangles
Let A' and A" be the areas of the triangles
let's calculate A' and A" :
The area of a triangle is the product of the base and the height over 2
- A' = = 60 mm²
- A"= = 108 mm²
Let's calculate A
- A = A' + A"
- A = 108+ 60
- A = 168 mm²
Answer:
D. 12
Step-by-step explanation:
D is the closest answer. -2 multiplied by a -1.8 is a +3.6. Then, you add 8 to 3.6 and you will get 11.6. Therefore, the answer you will put is D or 12
Answer:
Part A: Factor out the GCF. In this case, the GCF is 2y. So it looks like
2 x^3 * y+18xy-10 x^2 * y-90y=2y (x^3 - 5 x^2 + 9x-45)
Part B: The result from above will need to be factored by grouping.
Part C: If you switch the terms, the factoring will work out differently, but at the end, the factorization will be the same.
