What is the greatest<br> common factor (GCF) of 16<br> and 21

viktelen [127]

Answer:

Step-by-step explanation:

Let's start by prime factorizing (finding the prime factors) of 16 and 21:

$16=4*4=2*2*2*2=2^4$

$21=3*7$

We can see that they DO NOT have any common factors, meaning that their greatest common factor is 1.

Sin^22x - 2cos2x + 2=0

zhuklara [117]

Answer:

x=πn, n∈Z

Step-by-step explanation:

if sin²2x=1-cos²2x, then

1-cos²2x-2cos2x+2=0; ⇒ cos²2x+2cos2x-3=0; ⇔ (cos2x+3)(cos2x-1)=0;

$\left[\begin{array}{cc}cos2x+3=0\\cos2x-1=0\\\end{array} \ \ \left[\begin{array}{cc}x \ 'does-not-exist'\\cos2x=1\\\end{array} \ \ 2x=2\pi n, n=Z \ x=\pi n, n=Z$

Solve for xxx.<br> Your answer must be simplified.<br> x/7≥−6

uysha [10]

Answer:

x ≥ −42

Step-by-step explanation:

Let's solve your inequality step-by-step.

x/7≥−6

Step 1: Simplify both sides of the inequality.

$\frac{1}{7}x\geq -6$

Step 2: Multiply both sides by 7.

$7*(\frac{1}{7}x)\geq (7)*(-6)$

x ≥ −42
