2(
x + 4) = 
x + 4 which is the second option is the equivalent expression.
Explanation:
First, we need to calculate the value of two-fifths of x. It means 2 portions out of the five portions of x which equates to x.
Now we calculate the values of the two expresssions on the LHS.
1) 2 (two-fifths x + 2) = 2 (x + 2) = x + 4.
2) (two-fifths x + 4) = 2(x + 4) = x + 8.
Now we determine values of the four expressions on the RHS.
1) Two and two-fifths x + 1 = 2x + 1
2) Four-fifths x + 4 = x + 4
3) Four-fifths x + 2 = x + 2
4) Two and two-fifths x + 8 = 2x + 8.
Out of the various LHS and RHS values, the 
LHS value and 
RHS value is the same. So option 2 is the answer.
Answer:
(x - 6) • (4x - y)
Step-by-step explanation:
brainly???
Step by step solution :
Step 1 :
Equation at the end of step 1 :
(4x • (x - 6)) - y • (x - 6)
Step 2 :
Equation at the end of step 2 :
4x • (x - 6) - y • (x - 6)
Step 3 :
Pulling out like terms :
3.1 Pull out x-6
After pulling out, we are left with :
(x-6) • ( 4x * 1 +( y * (-1) ))
Final result :
(x - 6) • (4x - y)
Answer:
1005 ft squared (B)
Step-by-step explanation:
The far left area:
30*15=450
The middle area:
-Since there is an eight feet being subtracted it is:
22*15=330
The last side:
-Since there is two 15's at the bottom we must subtract 30 from 45:
15*30*1/2=225
Add the area together:
450+330+225=1005
1005 ft squared
Answer:
r = -3/7.
Step-by-step explanation:
To solve this equation, we multiply both sides by 6/7. This is the reciprocal of the coefficient in r (7/6) and will "cancel out" the expression. So:
-1/2 x 6/7 = -6/14 = -3/7.
As such, r = -3/7.
I hope this helps!
