Answer:
20
Step-by-step explanation:
Given the expression
x(x + 3) + 2 for x = 3
Substitute x =3 into the equation
f(3)= 3(3+3)+2
f(3) = 3(6)+2
f(3) = 18+2
f(3) =20
Hence the value of the expression when x = 2 is 20
Answer:
10
Step-by-step explanation:
6/6
This also means 6 out of 6. You can turn your question into a story problem to better understand the answer.
If you eat 6 out of 6 pieces of your cake you ate all of your cake.
With these types of problems you can always guess and check.
I know this is the right answer because 6÷6=1 (the fraction line is actually a division sign)
I might think it is 3/6 so I would do 3÷6=.5 or 1/2 but that is too small so I might try 4÷6 and so on until I get the correct answer (in this case the answer is 1)
Always keep in mind that if the numerator (top/first number) is bigger than the denominator (bottom/second number) the fraction will ALWAYS be greater than 1, if the numerator is less than the denominator the fraction is ALWAYS less than 1, and if the numerator is equal to the denominator the fraction is ALWAYS equal to 1.
Just remember to guess and check, make a story problem, or you can remember the rules about fractions I stated above.
I hope this has helped you not only to know the answer to your problem but to also understand future problems you may have!
Answer:
- Volume of cubiod= 108 in³
- TSA of cubiod = 168 in²
Step-by-step explanation:
<u>Given: </u>
Dimensions of cubiod :
- Length = 9 in.
- Breadth = 6 in.
- Height = 2 in.
<u>To Find:</u>
- Volume and Total surface area
<u>Solution</u>:
We know that,
So,
→ Volume = 9 × 6 × 2
→ Volume = 54 × 2
→ Volume = 108 in³
And,
- TSA of cubiod = 2(lb + bh + hl)
Substituting the values, we get:
→ TSA = 2(9 × 6) + (6 × 2) + (9 × 2)
→ TSA = 2(54 + 12 + 18)
→ TSA = 2 × 84
→ TSA = 168 in²
Hence,
- Volume of cubiod= 108 in³
- TSA of cubiod = 168 in²
