Answer:

x^2 + 8x + 12

Step-by-step explanation:

The area is in 4 parts:

x * x,

x * 2,

6 * x, and

2 * 6

So it is x^2 + 2x + 6x + 12, or

x^2 + 8x + 12

Answer:

x + y = 36 (1)

7x + 4y = 216 (2)

Step-by-step explanation:

Quanrity of Holiday blend = 36 pounds

Cost per pound of the blend = $6.00

Cost of chocolate chips = $7.00 per pound

Cost of pretzels = $4.00 per pound

Let

Pounds of chocolate chips = x

Pounds of pretzels = y

x + y = 36 (1)

7x + 4y = 36 × $6.00

7x + 4y = 216 (2)

The system of equation is

x + y = 36 (1)

7x + 4y = 216 (2)

Based on Pythagorean identities, which equation is true? sine squared theta minus 1 = cosine squared theta secant squared theta

Naddik [55]

Answer:

$Cot^2\theta-Csc^2\theta=-1$

Step-by-step explanation:

The only Pythagorean identities are:

$1. \ Sin^2\theta+Cos^2\theta=1$

$2. \ 1+Tan^2\theta=Sec^2\theta$

$3. \ 1+Cot^2\theta=Csc^2\theta$

$4. \ Sin^2\theta=1-Cos^2\theta\\ \ \ Cos^2\theta=1-Sin^2\theta$

Therefore, $Cot^2\theta-Csc^2\theta=-1$ is correct as it's one of the pythagorean identities.
