Erik used the Factor Theorem to find the remainder of 2x3-4x2-28x+6 divided by x+3. If he calculated the remainder to be 0, what does that tell him?
Step-by-step explanation:
x + 3 = 0
x = - 3
f(x) = 2x³ - 4x² - 28x + 6
f(- 3) = 2(- 3)³ - 4(- 3)² - 28 x (- 3) + 6
= 2 x (- 27) - (4 x 9) + 84 + 6
= - 54 - 36 + 90
= - 90 + 90
= 0
Therefore,
x + 3 is factor of 2x³ - 4x² - 28x + 6

Could someone please explain how to solve for the area?
9514 1404 393
Answer:
779.4 square units
Step-by-step explanation:
You seem to have several problems of this type, so we'll derive a formula for the area of an n-gon of radius r.
One central triangle will have a central angle of α = 360°/n. For example, a hexagon has a central angle of α = 360°/6 = 60°. The area of that central triangle is given by the formula ...
A = (1/2)r²sin(α)
Since there are n such triangles, the area of the n-gon is ...
A = (n/2)r²sin(360°/n)
__
For a hexagon (n=6) with radius 10√3, the area is ...
A = (6/2)(10√3)²sin(360°/6) = 450√3 ≈ 779.4 . . . . square units

Divide £60 in a ratio of 2:1
£40 and £20
Step-by-step explanation:
let the parts be 2x and x (2:1)
2x+x=£60
or, 3x= £60
or, x= £20
2x=2×£20=£40
x=£20
What is the value of 8m + 5n when m = 4 and n = 10?
Answer:
82
Step-by-step explanation:
m = 4
8m = 4 x 8 = 32
n = 10
5n = 5 x 10 = 50
32 + 50 = 82

Fathers age is twice his daughter age but 16 years ago fathers age was 4 times his daughters age . Calculate their ages
Answer:
Father's age = 48
Daughter's age = 24
Step-by-step explanation:
Let x be father's age and y be daughter's age.
1st equation:
x = 2y
2nd equation:
(x - 16) = 4(y - 16)
Replacing value of x from 1st equation,
(2y - 16) = 4(y - 16)
2y - 16 = 4y - 64
4y - 2y = 64 - 16
2y = 48
y = 48/2
y = 24
And,
x = 2y
x = 2 x 24
x = 48
8x - x = 64 - 16
7x = 48

Work out the Area of the shape
Answer:
145.8cm squared
Step by step:
16.2 divided by 3 = 5.4cm
In the second line where 2 bricks are horizontal and 2 are vertical:
2x + 3y = 16.2
3y = 16.2 - 2 x 5.4
y = 1/3 x 5.4
y = 1.8cm
Hence, height and length of each triangle is 1.8cm and 5.4cm
Complete length = 16.2 cm
Complete height = 2y + x = 2 x 1.8 + 3.4
= 9 cm
Area overall = 16.2 x 9 = 145.8cm squared
