Area of square base:
13 x 13 = 169
Area of triangular sides:
B x H/2
13 x 16/2 = 104
104 x 4 = because there are 4 triangular sides of the figure = 416
416 + 169 = 585in^2
590in^2
X=7
So 86 is your angle
(The right one)
Answer:
y=-2x^2-8x-6
Step-by-step explanation:
We already have two x intercepts (-3,0) and (-1,0):
(-3,0) is the solution to x+3=0
(-1,0) is the solution to x+1=0
So what we have so far is (x+3)(x+1)=y
Now we do (x+3)(x+1)*?=y
Plug in (-5,-16):
(-5+3)(-5+1)*x=-16
(-2)(-4)*x=-16
8*x=-16
x=-2
So the equation is y=(x+3)(x+1)*-2 which is y=-2x^2-8x-6
Another possible graph is y=(x+1)(x+3)(x+3) or y=x^3+7x^2+15x+9
Answer: answer is a
Step-by-step explanation:
The answer is 43 degrees.
Explanation:
Because that corner of the quadrilateral is equivalent to 90 degrees, the other angle would need to equal 90 when added together with 43.
To find the answer, you simply subtract 47 from 90, and you have found the answer, which, in this case, is 43 degrees.
Hope this helped! Have a good day.
