Answer:
c) 72
Step-by-step explanation:
multiply 18 by 4
Use BODMAS or BIDMAS (Brackets, over Indices, Division, Multiplication, Addition, the Subtraction, this tells you which order to do things in)
As you cant do √10 in the brackets you do the indices, so (√10)³
Split this up to make it easier
(√10)³= √10 x √10 x √10 = 10√10
You the multiply this by 9
9 x 10√10 = 90√10
then multiply by 5
5 x 90√10 = 450√10 = 1423.024947 (using calculator)
(g + h)(n) =
g(n) + h(n) =
2n + n^2 + 5 =
n^2 + 2n + 5 (standard form)
You are converting the numbers to a word problem.
1. 5+x = the number five plus x
2. 5-x= the number 5 minus x
3. 5x= five times x
4. 5/x= five divided by x
5. three-fourths of x plus 2
6. two minus three-fourths of x
7. 3 times x plus 10
8. ten times x plus three
