Answer:
(x - 2)(5x - 2)
Step-by-step explanation:
5x² - 12x + 4
consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term.
product = 5 × 4 = 20 and sum = - 12
the factors are - 10 and - 2
use these factors to split the x- term
5x² - 10x - 2x + 4 ( factor the first/second and third/fourth terms )
= 5x(x - 2) - 2(x - 2) ← factor out (x - 2) from each term
= (x - 2)(5x - 2) ← in factored form
The volume is 40
8x1x5=40

Use SOHCAHTOA. Since we are looking for the hypotenuse, you must use sine or cosine. Since, we are given the adjacent side, use cosine.
cosx=a/h
cos45=8/h
√2/2=8/h
<em>*Cross multiply*</em>
h√2=16
<em>*Divide both sides by √2*</em>
h=16/√2
<em>*Multiply by √2/√2*</em>
h=(16√2)/2
<em>*Simplify the fraction*</em>
h=8√2
Hope this helps!!
Your answer is b so there you go have a great day!!!!
Hey. Why are you so worried. Here is the answer. There is a very small problem.It is that the decimal point is not added.
