Answer:
Since you did not provide any other information, I did some research and might have found the original question/ answer choices. If this is the correct question, then your answer should be D.)
Surface Area of the square = 8 x 8 = 64 cm²
Surface Area of the 4 triangle = 4 x [ 1/2 x 8 x 14]
Surface Area of the 4 triangle = 4 x [ 56]
Surface Area of the 4 triangle = 224 cm²
Total Surface Area = 64 + 224 = 288 cm²
Answer: 288 cm²
Best to write this problem as shown below:
<span>562.34
-64.89
----------- First, estimate the correct answer. It would be 562-65 = 497.
Must borrow from the tenths column, because 9 is greater than 4. We end up with 5 under the 4 and 9. We must borrow again to obtain the next digit:
12-8=4, so the result is now .45
11-4=7, so the result is now 7.45
55-6=9, so the result is now 97.45.
Finally, 4-0=4, so the final result is 497.45. Compare this to the estimate (497).
Here we've had to borrow 4 times.</span>
Answer:
5x+2
Step-by-step explanation:
Ok so the expression 5(x+2) is not 5x+2 because you have to use the distributive property. So with that being said:
5(x+2)=5 times x and 5 times 2
so the realest answer is 5x+10 instead of 5x+2
