The area of the rectangle is 18 , I didn't understand the equation fully so I did (4*4.5=18) because (1/2=.5) .
Hope this helps
Answer:
Step-by-step explanation:
<u>Shaded region (blue) is the difference of areas of big and small triangles</u>
- A = 1/2(16*12 - 10*6) = 66 cm²
<em>The answer options are incorrect</em>
We can solve it like:
3x^3+3x^2+x+1= (3x^3+3x^2)+(x+1)=
3x^2(x+1)+(x+1)=
= (x+1)(3x^2+1)
Have a good day
Answer:
4/5
Step-by-step explanation:
Sin = Opposite / Hypotenuse
Note that hypotenuse = longest side
We want to find sinФ
The opposite side length of angle "Ф" has a length of 8 and the longest side or hypotenuse has a length of 10
So sinФ would equal 8/10 which can be simplified to 4/5
