What is 4n plus 2 times 5n minus one?
20n2+6n-2 (4n + 2)(5n -1) This problem can be solved by FOILing. First, multiply the first terms to get 20n2 Next, multiply the outside terms to get -4n. Multiplication of the inside terms results in 10n. Combining -4n and 10n (they are like terms) is 6n. Then, multiply the last terms, to get -2. Combining these answers into one equation gives the answer of 20n2+6n-2.
How many integers between 197 and 303 divisible by 4?
An=A¹+(n-1)d 300=200+(n-1)4 300-200=4n-4 100+4=4n ¼(104=4n) 26=n An=A¹+(n-1)d 300=200+(n-1)10 300-200=10n-10 100+10=10n ⅒(110=10n) 11=n Find the least common multiple of (4,10) 4 8 12 20 24 10 20 30 LCM=20 Then we are going to find the numbers between 200 and 300 that are divisible by 20. 200, 220, 240, 260, 280, 300 We have 6 numbers 26+11=37-6= 31 The answer is 31
