Answer:
60
Step-by-step explanation:
<C+<D = 180 since they form a straight line
5x+20 +3x = 180
8x+20 = 180
Subtract 20 from each side
8x+20-20 = 180-20
8x = 160
Divide by 8
8x/8 = 160/8
x = 20
We want to find angle D
<D = 3x= 3*20 = 60
A(x) = (3000-x)/2 * x
a(x)=(1500-½x)*x
a(x)=1500x-½x²
Answer is (B)
Explanation:
M<2=180-53x2
=74
M<2=5x+14=74
5x=60
X=12
Answer:
The ratio means that for every 9 boys there are 10 girls
Step-by-step explanation:
G(x) appears to be a vertical expansion of f(x) by a factor of 3. f(x) appears to be
.. f(x) = x²
so g(x) would be
.. g(x) = 3x²
