Answer:
684 sq.ft
Step-by-step explanation:
(1) The base area of the pyramid is 18x20=360 sq.ft
(2) The Triangles of the pyramid:
1. There are two kinds of the triangles.
2. Smaller one: 18x8/2 (base times height divide 2)=72 sq.ft
3. Bigger one: 20x9/2=90 sq.ft
4. There are two of them so 72+72+90+90=324 sq.ft
And so 360+324=684 sq.ft.
I think the answer is 2,2 I’m not sure
Answer:
6x+2
Step-by-step explanation:
your combine like terms...
so 13x is teh same as -7x
13x-7x= 6x
3 and -1 are the same as well
3-1=2
so teh answer would be
6x+2
The 1st graph has vertex in (-3, -3) which can be translated into
Horizontal shift left 3
Vertical shift down 3
Other than that, the graph shows y=x^2 so it wasn't compressed or stretched
The 2nd graph has vertex in (0, 0) which mean there is no vertical and horizontal shift. But the graph is facing down and it was slimmer than y=x^2 graph. When x=1, the result is y=3 which was 3 times more than it supposed to be.
The graph must be:
Reflection across x-axis
Vertical stretch of 3
The 3rd graph has vertex in (3, -3) which can be translated into
Horizontal shift right 3
Vertical shift down 3
Same as the 1st graph, the 3rd graph shows y=x^2 so it wasn't compressed or stretched.
