Answer:
(4x² + 3)(16
- 12x² + 9)
Step-by-step explanation:
A sum of cubes factors as
a³ + b³ = (a + b)(a² - ab + b²)
64
= (4x²)³ ⇒ a = 4x²
27 = 3³ ⇒ b = 3
Hence
64 + 27
(4x² + 3)((4x²)² - (4x² × 3) + 3²)
= (4x² + 3)(16 - 12x² + 9)
Answer:
<em>(7, 11)</em>
Step-by-step explanation:
y = 2x - 3 .... (1)
x + y = 18 .... (2)
(1) ----> (2)
x + 2x - 3 = 18 ⇒ <u><em>x = 7</em></u>
y = 2(7) - 3 ⇒ <u><em>y = 11</em></u>
<em>(7, 11)</em>
Answer:
For a circle of radius R, the circumference is:
C = 2*pi*R
where pi = 3.14
And if we have an arc defined by an angle θ, the length of the arc is:
A = (θ/360°)*2*pi*R
Here we can not see the image, then i assume that B is the angle that defines the arc AC.
Now we know that the circumference is 120 in, then:
2*pi*R = 120in
Then the length of the arc is:
A = (θ/360°)*120 in
Then if the angle is 18°, we have:
A = (18°/360)*120 in = 6in
