Answer:
a
Step-by-step explanation:
because for a 45-degree right triangle the two legs are the same and because the legs are sqrt 3, it is sqrt 6
Surface Area is the area of each face added together. For this question lets find the area of one triangle first.
Area of a triangle is base*hight/2, so 6*7/2=21. That was the area of one triangle. We have 4 traingle so we multiply that by for. 21*4=84.
Now, lets find the area of the squre. area of square is side*side or side^2.
So we multiply 6*6=36. that is the area of the square.
To find the surface area, we must add Area of Triangles+Area of Square.
so, 84+36=120
So the surface area is 120
Answer:
3x² + 9x + 6
Explanation:
(3x + 3)(x + 2)
= (3x + 3)(x + 2)
= (3x)(x) + (3x)(2) + (3)(x) + (3)(2)
= 3x² + 6x + 3x + 6
= 3x² + 9x + 6
