Answer:
x = -3
Step-by-step explanation:
5 = x + 8
You need to get x by Itself so subtract 8 to both sides.
5 - 8 = -3
so therefore x = - 3
(x + 3) (2x – 7) = 0
What is this ?
factorize:-
x³–3x²–9x–5
no links or spam answers please!
Answer:
X³ – 3x² – 9x – 5
= x³ + x² – 4x² – 4x – 5x – 5
= x²( x + 1) – 4x ( x + 1) – 5(x + 1)
= (x + 1)(x² – 4x – 5)
= (x + 1)(x² -5x + x – 5)
= (x + 1)(x – 5) (x + 1)
hence, (x +1), (x -5) and (x +1) are the factors of given polynomial .

Helen has 2 winter coats, 4 hats and 3 scarves. How many different outfit combinations does Helen have to chose from?
Given:
Number of winter coats = 2
Number of hats = 4
Number of scarves = 3
To find:
The total number of different outfit combinations.
Solution:
Number of winter coats is 2. So, the number of ways to select a winter coat from 2 coats is 2.
Number of hats is 4. So, the number of ways to select a hat from 4 hats is 4.
Number of scarves is 3. So, the number of ways to select a scarf from 3 scarves is 3.
So, the total number of ways is:
[tex]2\times 4\times 3=24[/tex]
Therefore, Helen have 24 different outfit combinations.
can someone please help me
Answer:
B
Step-by-step explanation:
its a right angle and one point is 40 as shown already so 90-40=50 hope this helps
So you would take your 90° angle which is the box on the bottom right hand corner and add 40° which would equal 130° and then you would subtract 180° -130° and you would get 50°.

Solve for X ...........
Answer:
x = 46
Step-by-step explanation:
Given 2 secants from an external point to the circle, then
The product of the external part and the whole of one secant is equal to the product of the external part and the whole of the other secant, that is
2(2 + x) = 6(6 + 10)
2(2 + x) = 6 × 16 = 96 ( divide both sides by 2 )
2 + x = 48 ( subtract 2 from both sides )
x = 46

Andre can run 2 1/2 miles in 3/4 hour. Find his average speed in miles per hour
Answer:
3 1/3 miles per hour
Step-by-step explanation:
's' = average speed
(5/2 ÷ 3/4) = (s ÷1)
(5/2 ÷ 3/4) = 10/3
10/3 = s/1
cross-multiply:
3s = 10
s = 10/3
s = 3 1/3 miles per hour

Can anybody do these for me hurry ?
Answer:
- Mode-The most repetitive number.
- Median:The number in the MIDDLE when they are IN ORDER.
- Mean- The AVERAGE OF ALL NUMBERS: You add up all the numbers then you divide it by the TOTAL NUMBER of NUMBERS.
- Range - THE BIGGEST minus the Smallest.
Step-by-step explanation:
;)
Answer:
mean: average of all the numbers, so add all numbers, divide by the amount of numbers you added
median: sort all the numbers from least to greatest, then the middle is the answer, if there are 2 in the middle, both are the answer
mode: the number that appeared most
range: the largest number minus the smallest number

Answer:
[tex]140[/tex]
Step-by-step explanation:
A regular polygon is a shape with equal sides and angles. Because of this, we can write the following equation to set two sides equal to each other:
[tex]3a+b+3=2a+2b+6[/tex]
Solving, we will get a in terms of b:
[tex]3a=2a+b+3,\\a=b+3[/tex]
Now we can substitute a for (b+3) into our equation:
[tex]5a-2b+1=2a+2b+6,\\5(b+3)-2b+1=2(b+3)+2b+6,\\3b+16=4b+12,\\-b=-4,\\b=\boxed{4}[/tex]
Therefore, the length of each side of this polygon is [tex]5(4+3)-2(4)+1=28[/tex].
Since the perimeter of the polygon consists of all five sides, the perimeter is:
[tex]p=28\cdot 5 =\boxed{140}[/tex]
