The answer would be x^2-18x+81. This can be found be writing "(x-9)^2" twice, and distributing. Combine like terms, and you should get this answer.
Short answer : x = -13/3
But let's solve your equation step-by-step.
-2(x+8)=4x+10
Step 1: Simplify both sides of the equation.
(Distribute)
Step 2: Subtract 4x from both sides
Step 3: Add 16 to both sides.
Step 4: Divide both sides by -6.
Answer:
x = -13/3
Substitute the value of s, which is now 3 into the equation
A = 6(3)^2
A =6(9)
A = 54
Answer:
<h2><u><em>
2.8 miles</em></u></h2>
Step-by-step explanation:
Josh runs 7 miles in 60 minutes. At the same rate, how many miles would he run in 24 minutes?
7 : 60 = x : 24
x = 7 * 24 : 60
x = 2.8 miles
