Answer:
Lateral = 48 cm squared and Surface area = 60 cm squared
Step-by-step explanation:
Lateral surface area = 4 x 4 + 5x4( Slope) + 4 x 3 (Cross section x2) = 48
Surface area: Lateral + 4x3(base)
Like terms have the same variable and power. The simplification of the expression (6x²-3-5x³)-(4x³+2x²-8) is -9x³+4x²+5.
<h3>What are Like terms?</h3>
Like terms are those terms that are having the same variables, also the variables are of the same order as well.
for example, 25x and 5x are like terms; 30xy and 7xy are like terms, 9x³ and 4x² are not like terms, etc.
We know that to simplify an expression we need to add or subtract like terms, therefore,

Hence, the simplification of the expression (6x²-3-5x³)-(4x³+2x²-8) is -9x³+4x²+5.

Answer:
0.9%
Step-by-step explanation:
We have been given that Rich measured the height of a desk to be 80.7 cm. The actual height of the desk is 80 cm.
We will use percentage error formula to solve our given problem.





Therefore, Rich's percent error in calculation is 0.9%.
The probability that will not rain today is: 85%
100% - 15% = 85%
The correct answer is A
