i would say -6a^6*9
do 3 x -2 and get -6 then leave the exponent as 6 because you dont do anything with them but leave them the same
Answer:
the side lengths will be 4√2- 4√2 - 8
Step-by-step explanation:
When you have missing side lengths of a right triangle, you can use special triangles to find the side lengths. Where the angles are 45-45-90, each triangle has side lengths with the relationship 1 - 1 -√2.
This means for problem 9, the side length 8 is the equivalent of the special triangle √2 * √32 = √64 = 8. So each side is multiplied by √32.
So the side lengths will be 4√2- 4√2 - 8.
These are found using:
1*√32 = √32 = 4√2
1*√32 = √32=4√2
√2*√32 = √64 = 8
Let w represent the number of weeks Emma saves her money. Then we want to find w for
60 +22w ≥ 249
22w ≥ 189 . . . . . . . . . subtract 60
w ≥ 189/22 ≈ 8.591
Emma will have enough money after 9 weeks.
3.
√250 = √(25 * 10) = √(5^2 * 10) = √(5^2) * √10
… = 5 √10
=> <em>a</em> = 5
4.
√(-300) = √(-1 * 3 * 100) = √(-1 * 3 * 10^2) = √(-1) * √3 * √(10^2) = <em>i</em> * √3 * 10
… = 10<em>i</em> √3
=> -<em>a</em> = 10 and <em>b</em> = 3 => <em>a</em> = -10 and <em>b</em> = 3
=> <em>a</em> - <em>b</em> = -10 - 3 = -13
