Well, notice the composite is really just 4 triangles atop sitting on top of 4 rectangles, and all of them area stacked up at the edges.
so, for the rectangle's sides,
front and back are two 6x3 rectangles
left and right are two 6x3 rectangles
the bottom part is a 6x6 rectangle
now, we don't include the 6x6 rectangle that's touching the triangles, because that's inside area, and is not SURFACE area, so we nevermind that one.
now, the triangles are just four triangles with a base of 6, and a height of 4, in red noted there.
so, just get the area of all those rectangles and the triangles, sum them up and that's the
surface area of the composite,
Answer:
240
Step-by-step explanation:
V=width height length = 10 · 3 · 8 = 240
Hope this helped, have a wonderful day man!
The expression xy-2, when x=3 and y= -4, becomes (3)(-4)-2, or -14 (answer)
the expresion 3x^2*y - 4 becomes 3(3)^2*(-4) - 4, or 27(-4) - 4, or -108 - 4 = -112 (answer)
Leave Timmy out of this, since it seems he didn't really do anything. ;)
Answer:
n = 35 more returns to prepare
Step-by-step explanation:
6240 - 640 = amount
still to be earned = 160n
5600=160n
n = 35
4. The following set of points belong to a specific function: {(-3,0)(-2,4), (-1,0 ), (0,-6),(1,-8), (2,0),(3,24)} Based on the
notsponge [240]
The type of function that these sets of points are known to produce is the cubic function.
<h3>What is a cubic function?</h3>
This is a function that is known to be a polynomial of degree 3. This type of polynomial is one that the coefficients are known to be complex numbers.
This is a cubic function given that the x axis is known to go through these points (-3,0), (-1,0), (2,0).
b. Given the sets of pints that we have, we have the equation
f(x) = a(x+3)(x+1)(x-2)
Such that
f = -2 =
4 = a x 1 x -1 x -4
4 = 4a
a = 1
