-3

-1

ExplanationSubstitute x = -2 into the equation: 3(-2)^2 + 2(-2) - 5 = 3(4) - 4 - 5 = 12 - 9 = 3.

-2

-4

ExplanationRewrite in slope-intercept form (y = mx + b): -2y = -4x - 8, which simplifies to y = 2x + 4. The slope m is 2.

486

450

420

466

ExplanationLet numbers be x and y. x+y=45, x-y=9. Adding gives 2x=54, x=27. y=18. 27 * 18 = 486.

-2

Explanationlog(x^2 - 3x) = 1 implies x^2 - 3x = 10. x^2 - 3x - 10 = 0. (x-5)(x+2)=0. Since log must be positive, x=5.

11π

121π

44π

484π

ExplanationCircumference = 2πr = 22π, so r=11. Area = πr^2 = π(11^2) = 121π.

Equilateral

Isosceles

Right-angled

Obtuse

ExplanationCheck Pythagorean theorem: 7^2 + 24^2 = 49 + 576 = 625 = 25^2. Since a^2+b^2=c^2, it is right-angled.

cos(2x)

sin(2x)

-sin(2x)

cos^2(x) - sin^2(x)

Explanationf(x) = 0.5 * sin(2x). Derivative is 0.5 * cos(2x) * 2 = cos(2x).

Undefined

ExplanationFactoring the numerator gives (x-1)(x+1)/(x-1). Canceling (x-1) leaves x+1. Plugging in 1 gives 2.

-2

-10

ExplanationDeterminant = (ad - bc) = (1*4) - (2*3) = 4 - 6 = -2.

x + C

x^2 + C

2x^2 + C

x^2/2 + C

ExplanationUsing the power rule for integration, the integral of x^n is x^(n+1)/(n+1). Here, integral of 2x^1 = 2 * (x^2/2) = x^2.

-1

-i

ExplanationBy definition, the imaginary unit i satisfies the equation i^2 = -1.
