Rectangle
Step-by-step explanation:
All its angles measure 90 degrees or are right angles and one pair of side lengths are longer then the other
Answer:
50.2 m²
Step-by-step explanation:
The area (A) of a circle is calculated as
A = πr² ( r is the radius , here r = 4 ), thus
A = π × 4² = 16π = 16 × 3.14 ≈ 50.2 ( to the nearest tenth )
Yes the answer is 14 good job
Answer:
3 items are in B that are not in C
Step-by-step explanation:
a: only in a, not count those in b or c
b: only in b, not count those in a or c
c: only in c, not count those in a or b
A = a + b + c = 20
c = 7
a + b = 20 - 7 = 13
10 not in b, of course not in c ∴ a = 10
b = 13 -10 = 3
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
