So step one is to distribute the 4x through and the -5 through. After distributing you get 8x^{2}+28x-15x+10. Combine the like terms, 28x and -15x, to get 13x. Your answer is 8x^{2}+13x+10
Answer:
6 + 0.05
Step-by-step explanation:
To write a number in expanded form, you write each value of the digits by themselves. For example, let us say that that the number is 250.96 . To write in expanded form, you are essentially stretching out all the non-zero numbers, and keeping them separate (but in the same value), As in the example, we will write it out as expanded form:
250.96 = 200 + 50 + 0.9 + 0.06

Answer:
For example, suppose we weigh five children. ... 5. ∑ i=1 xi. = x1 + x2 + x3 + x4 + x5. = 10 + 12 + 14 + 8 + 11. = 55. ... We also use sigma notation in the following way: 4 ... j2 = 12 + 22 + 32 + 42 = 30.
