Answer:
and 4![\sqrt{11}](https://tex.z-dn.net/?f=%5Csqrt%7B11%7D)
Step-by-step explanation:
To simplify like surds, add/ subtract the coefficients.
(a)
(6 - 5)
=
(1)
= ![\sqrt{2}](https://tex.z-dn.net/?f=%5Csqrt%7B2%7D)
(b)
( 1 + 3)
=
(4)
= 4![\sqrt{11}](https://tex.z-dn.net/?f=%5Csqrt%7B11%7D)
(a)(b) = x
a = -65
b = 8
(-65)(8) = x
x = -520
x = -520 is your answer
hope this helps
Answer:
see explanation
Step-by-step explanation:
x = r cosΘ
y = r sinΘ
with r = 54 and Θ = 69°, thus
x = 54cos69° ≈ 19.4
y = 54sin69° ≈ 50.4
Thus (54, 69° ) as an ordered pair
= ![\left[\begin{array}{ccc}19.4\\50.4\\\end{array}\right]](https://tex.z-dn.net/?f=%5Cleft%5B%5Cbegin%7Barray%7D%7Bccc%7D19.4%5C%5C50.4%5C%5C%5Cend%7Barray%7D%5Cright%5D)
