Answer:

8 sqrt(5)

Step-by-step explanation:

sqrt(45) + sqrt(125)

Rewriting

sqrt(9*5) + sqrt( 25 *5)

we know sqrt(ab) = sqrt(a) sqrt(b)

sqrt(9) sqrt(5) + sqrt(25) sqrt(5)

3 sqrt(5)+5 sqrt(5)

Add like terms

8 sqrt(5)

Write a polynomial function of minimum degree with real coefficients whose zeros include those listed. Write the polynomial in s
chubhunter [2.5K]
This is a polynomial of degree 4, because you have 4 roots real or imaginary:1st) x= 5 →(x-5)=0
2nd) x = - 3→(x+3) =0
3rd) x = -1+3i →(x+1-3i) = 0
and the 4th one that is not mentioned which is the conjugate of 
-1+3i, that is -1-3i (in any polynomial if a root has the form of a+bi, there is always a conjugate root = a-bi)
 
4th) x= -1-3i→(x+1+3i) = 0
Hence the polynomial =(x-5)(x+3)((x+1-3i)(x+1+3i)
Solving the above will give you (unless I am mistaken, pls recalculate):

x⁴-9x²-50x-150<u />

Find the area of the rectangle as a single expression.
qwelly [4]

Answer:

D) 15x^2 +6x-48

Step-by-step explanation:

Area \:  of  \: rectangle  \\  = length \times width \\  = 3(x + 2) \times (5x - 8) \\  = (3x + 6) \times (5x - 8) \\  = 3x(5x - 8) + 6(5x - 8) \\  = 15 {x}^{2}  - 24x + 30x - 48 \\  = 15 {x}^{2}  + 6x - 48

Can someone please explain to me the difference between SAS and SSS in Geometry when dealing with triangle proofs?
ANTONII [103]

Hello from MrBillDoesMath!

Answer:   SAS = side - angle -side    congruence

              SSS  = side - side - side     congruence


Discussion :

In Plane Geometry,  identical triangles are said to be "congruent". There are several ways, depending upon the information you have, to prove 2 triangles are congruent.

In one approach ("SSS") if you can show that 2 triangles have identical side lengths,  then the triangles are congruent. (A triangle has 3 sides, hence "SSS" -- 3 S's; 3 sides, get it?)

In another approach ("SAS") if you can show that 2 sides, and the angle included between those sides, in one triangle are identical to the sides and included angle in another triangle,  then the triangles are congruent

It's easier to understand this with a picture or diagram than in words. Please review the SSS, SAS picture in your textbook
