In this case they are like terms as both terms have x.
To simplify the expression we add the coefficients. Doing so, we have:
4. 78x + x = 5.78x
The answer is 5.78x
ok but what's the problem?
Answer:
1.752
Step-by-step explanation:
Nine tenths = 0.9
0.852 + 0.9 = 1.752
Answer: D. 84 ft^2
Step-by-step explanation: The area of a trapezoid is (a+b)/2 x h. A and B are the bases, and h is the height. Plug in the numbers.
(8+16)/2 x 7 = 84
Your answer would be 84 ft^2. D.
