Factor completely<br> 6n2 – 11n – 10

Pepsi [2]

Step-1 : Multiply the coefficient of the first term by the constant 6 • -10 = -60

Step-2 : Find two factors of -60 whose sum equals the coefficient of the middle term, which is -11 .

-60 + 1 = -59

-30 + 2 = -28

-20 + 3 = -17

-15 + 4 = -11 That's it

Step-3 : Rewrite the polynomial splitting the middle term using the two factors found in step 2 above, -15 and 4

6n2 - 15n + 4n - 10

Step-4 : Add up the first 2 terms, pulling out like factors :

3n • (2n-5)

Add up the last 2 terms, pulling out common factors :

2 • (2n-5)

Step-5 : Add up the four terms of step 4 :

(3n+2) • (2n-5)

Which is the desired factorization

Final result :

(2n - 5) • (3n + 2)

In the accompanying diagram of circle O, chords AB and CD intersect at E and

RoseWind [281]

Answer:

m(arc AC) = 72°

m(arc BD) = 108°

m∠DEB = 90°

Step-by-step explanation:

Ratio of the measure of arc AC, arc BC, arc BD and arc AD = 4 : 2 : 6 : 8

Since, m(arc AC) + m(arc CB) + m(arc BD) + m(arc AD) = 360°

By the property of ratio,

Measure of arc AC = $\frac{4}{4+2+6+8}\times (360^0)$

= $\frac{4\times 360}{20}$

= 72°

Measure of arc BD = $\frac{6}{4+2+6+8}\times (360^0)$

= $\frac{6\times 360}{20}$

= 108°

Measure of ∠DEB = $\frac{1}{2}m(arcAC + arc BD)$

= $\frac{1}{2}(72+108)$

= 90°

Given b(x)=√3x+3 evaluate f(11) I really need help with this.

andre [41]

Step-by-step explanation:

$\huge{\purple{\underline{\underline{\bf{\pink{Answer}}}}}}$

in we have x = 11

put the value of x in equation

$b(11) = \sqrt{3} (11) + 3$

$b(11) = 11 \sqrt{3} + 3$

so x = 11√3

Hope it helps
