Answer:
5 and 6
Step-by-step explanation:
-5 x 6 = -30
-5 + (6) = 1
x2 + 1x - 30 = 0
(X - 5 ) (X + 6)
To summarize, since -5 and 6 multiply to -30 and add up 1, you know that the following is true:
x2 + 1x - 30 = (X - 5 ) (X + 6)
Answer:
16.6%
Step-by-step explanation:
(75/89.95)*100=83.37....
100-83.37...=16.62...
=16.6%
If you would like to solve y = x - 4 and 2 * x + y = 5, you can do this using the following steps:
y = x - 4
2 * x + y = 5
_____________
2 * x + (x - 4) = 5
2 * x + x = 5 + 4
3 * x = 9 /3
x = 9 / 3
x = 3
y = x - 4 = 3 - 4 = -1
The correct result would be x = 3 and y = -1.
Answer:
30.67 feet
Step-by-step explanation:
A proportion is often useful for solving scale drawing problems.
actual size : drawing size = (room length) : (23 in) = (2 ft) : (1.5 in)
Multiplying by 23 in gives ...
room length = (2 ft)(23 in)/(1.5 in) = 46/1.5 ft = 30 2/3 ft
room length ≈ 30.67 ft.
The answer is 90 I think I multiplied 6*3 =18 *4 =72( for every rectangle )then 3*3 =9 for the square (2 squares ) 9*2=18
