Answer:
x² - 6x = -5
x = {1, 5}
Step-by-step explanation:
The square of a number minus six times a number equals negative five.
x² - 6x = -5
Add 5 to both sides
x² - 6x + 5 = 0
Factor
(x - 1)(x - 5) = 0
x = {1, 5}
Pythagorean theorem: a^2 + b^2 = c^2
The hypotenuse is always the c in the equation.
If the two side lengths they gave you are not the hypotenuse, then enter
4.5^2 + 5.6^2 in the calculator, then find the square root of that. :-)
Answer:
1.835
Step-by-step explanation:
use pythagoras theorem to find missing side
use sin to find missing angle
missing side/13 = 1.835
Step-by-step explanation: Arrange the terms in ascending order: -7, -2/5, 3/9, 11/12.
Hope this helps! :D

Answer:
Step-by-step explanation:
Hello!
a)
- 11.5= a
b)
b= -11 -7 = -18
c)
c+3 = 15
c = 15 -3 = 12
d)
-4d = 32
d = -32/4 = -8
