Answer:
If x+8 is a factor, divide by -8.
-8 1 18 80
-8 -80
_______________
1 10 0
It is a factor because there is no remainder.
Step-by-step explanation:
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 .

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

a ramp measures 6 feet long. if the ramp is 12 inches tall, what is the horizontal distance it covers? i'll give brainliest to whoever answers first/correctly!
we know that
1 ft--------> is equals to 12 in
the ramp is 12 inches tall----------> 1 ft tall
A ramp measures------------------> 6 ft long
applying the Pythagorean theorem
c²=a²+b²
where
c-----> 6 ft long
a----> horizontal distance
b-----> 1 ft tall
a²=c²-b²------> a²=6²-1²-----> a²=35------> a=√35------> a=5.92 ft
the answer is
5.92 ft
Answer:
6.08 or so
Step-by-step explanation:
The height is 1 foot, while the length is 6 feet.
You can use the Pythagorean Theorum to solve this, as you plug in the values.
The theorum states that A squared plus B squared = C squared, where A is the length, and B is the width. (It doesn't matter if A is the width and B is the length either.)
So if we plug in the values:
1 squared plus 6 squared = C squared.
1 + 36 = 37
Since it is C squared, we can find the square root of 37, which is something like 6.0827625302982196889996842452021.
So usually we round to the hundredths place, so we can use 6.08.
A square is split into four
similar squares, one of
the new squares is split
into fourths again, and
this process continues.
What kind of sequence
does this demonstrate?
Answer:
Geometric Sequence.
Step-by-step explanation:
We are told that the square is split into 4 similar squares. One of the new squares is now split into fourths again and this same sequence is repeated over again.
This means that there is a common ratio which is ¼.
Since there is a common ratio and not common difference, this sequence is said to be a geometric sequence.

Answer:
sin A = 13/85
Step-by-step explanation:
Opposite Angle A is side BC, of length 13. The length of the hypotenuse is 85. The sine function is defined as the ratio opp/hyp. In this problem that ratio is
opp
------ = sin A = 13/85
hyp
We use the inverse sine function arcsin x to determine Angle A:
A = arcsin 13/85 = 8.8 degrees
Answer:
Sin(A) = [tex]\frac{13}{85}[/tex]
Step-by-step explanation:
Sin ratio = [tex]\frac{opposite}{hypotenuse}[/tex] (according to the given or asked angle)
Sin (A) = [tex]\frac{13}{85}[/tex]

A circular pool has a footpath around the circumference. The equation x2 + y2 = 2,500, with units in feet, models the outside edge of the pool. The equation x2 + y2 = 3,422.25, with units in feet, models the outside edge of the footpath. What is the width of the footpath?
Answer:
8,5 feet
Step-by-step explanation:
The equation of the form
x² + y² = (r)²
Is the equation of the circumference
We have for the pool:
x² + y² = 2500 ⇒ x² + y² = (50)²
And for the outside edge of the footpath
x² + y² = 3422,25 ⇒ x² + y² = (58,5)²
So we obtain the radius of each circumference
For the outside edge of the pool r₁ = 50 feet
For the outside edge of the footpath r₂ = 58,5 feet
Then the width of the footpath is 58,5 - 50 = 8,5 feet
6.) Evaluate the expressions below for the given values.

b. n 2+ n + 1 for n = 8
c. (r – 10)(r + 2) for r = 13
20 POINTSS
Answer:
Answer below. Hope it helps.
Step-by-step explanation:
a. 2x + (x - 6) {x = 14}
= 2*14 + (14 - 6)
= 28 + 8
= 36
b. n² + n + 1 {n = 8}
= 8² + 8 + 1
= 64 + 9
= 73
c. (r - 10) (r + 2) {r = 13}
= (13 - 10) (13 + 2)
= 3 * 15
= 45

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.

Harry pays a tv priced £1200 plus VAT 20%. He pays £300 deposit and the balance in 10 equal monthly payments calculate the monthly payment
Answer:
£114
Step-by-step explanation:
total price of the tv = cost + tax
tax = o.2 x 1200 = 240
total price = 1200 + 240 = 1440
monthly payment = 1/10 x (1440 - 300) = 114
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°.
Choose the diagram that shows the graph of the inequality.
