For this case we must factor the following quadratic expression:

To factor, we must find two numbers that when multiplied give as result +9 and when added or subtracted give as result -6.
These numbers are:
-3 and -3

So, we have:

ANswer:
Option D
The product of two rational numbers is another rational number.
The product of one irrational number and any other number is
irrational, even if the other one is rational.
The product of any two real numbers is never imaginary,
whether either or both of them is rational or irrational.
The product of two numbers is sometimes an integer
and sometimes not an integer.
Answer:
320
Step-by-step explanation:
Area base = Area rectangle + area triangle = 6*8 + (1/2)*8*4
Volume prism= Area base*height = [6*8 + (1/2)*8*4]*5 = 320 cm³
Answer:
x ≈ 37.53
Step-by-step explanation:
To find the value of x, we will follow the steps below:
first, we need to find angle z
z+47° +90° = 180° (sum of interior angle of a triangle)
z + 137° = 180°
subtract 137° from both-side of the equation
Z + 137°-137° = 180° - 137°
Z=43°
angle Z = 43°
We can now use the sine rule to find the value of x
Using the sine rule

where Z and X are angles and z and x are side length
from the diagram given,
X = 47° and we find Z to be 43°
side z = 35
we can now proceed to substitute the values into the formula
= 
cross-multiply
x sin 43° = 35 sin 47°
divide both-side of the equation by sin 43°
x sin 43° /sin 43°= 35 sin 47° /sin 43°
x ≈ 37.53 to two decimal place
