Answer: 6x(x+2)
6x X x= 6x squared
And 6x X 2= 12x
Answer:
Yes, the solids are similar.
Step-by-step explanation:
To figure this out you have to test the ratios of the corresponding dimensions. If they are all equal, they are similar.
28/21=1.33333
22/16.5=1.33333
24/18=1.33333
As they all equal 1.33333, the solids are similar
Answer:
14
Step-by-step explanation:
you can do this two ways:
<u>First: </u>
<u>Second: </u>
Distribute the 3 first
Solution :
2a + 2b = 7 ...1)
4a + 3b = 12 ...2)
In equation, 1)
a = (7 - 2b)/2 ...3)
Putting value of a in equation 2) we get :
4 × (7 - 2b)/2 + 3b = 12
2( 7 - 2b ) + 3b = 12
14 - 4b + 3b = 12
b = 2
Putting value of b in 3) we get :
a = ( 7 - 2×2)/2
a = 3/2 = 1.5
Now,
2x - 3y = 16 ...5)
x + 2y = -6 ...6)
x = -6 - 2y
Putting above value of x in eq 5) , we get :
2( -6 - 2y ) - 3y = 16
-12 - 4y - 3y = 16
7y = -28
y = -4
x = -6 - ( 2× -4 )
x = 2
Hence, this is the required solution.
Alright, here we go ;)
10000=5000*1.07^10.2
40000=5000*1.07^x
Systems of equations and solve.
The answer is D.
