complete the process of solving the equation. fill in all missing terms and select all missing descriptions. simplify any fractions. 2(2d + 10) = 20 4d + 20 = 20 4d = 0 subtract 20 from both sides d = 0 divide both sides by 4
Answer
Explanation:
Step1: Expand the left - hand side
Use the distributive property (a(b + c)=ab+ac). Here (a = 2), (b = 2d), (c = 10), so (2(2d + 10)=2\times2d+2\times10=4d + 20).
Step2: Isolate the variable term
Subtract 20 from both sides of the equation (4d+20 = 20). We get (4d+20 - 20=20 - 20), which simplifies to (4d=0).
Step3: Solve for (d)
Divide both sides of the equation (4d = 0) by 4. So (\frac{4d}{4}=\frac{0}{4}), and (d = 0).
Answer:
The missing description for (4d + 20 = 20) is "Use the distributive property". The completed solution shows that (d = 0).
