Ok so the base length is 8, the height is 2.72.

So 1/2 * 8 *2.72 should get u the answer.

Answer:

Step-by-step explanation:

$x^2-6=16x+30\\\mathrm{Subtract\:}30\mathrm{\:from\:both\:sides}\\x^2-6-30=16x+30-30\\Simplify\\x^2-36=16x\\\mathrm{Subtract\:}16x\mathrm{\:from\:both\:sides}\\x^2-36-16x=16x-16x\\\Simplify\\x^2-16x-36=0$

Step-by-step explanation:

Step 1: Define

$\displaystyle f(x) = 2(4)^x\\f(-2) \ is \ x = -2$

Step 2: Evaluate

Substitute in x: $\displaystyle f(-2) = 2(4)^{-2}$
Exponents: $\displaystyle f(-2) = 2(\frac{1}{16})$
Multiply: $\displaystyle f(-2) = \frac{1}{8}$

I need help! Will this would be very appreciated!pls

Answer:

No real

solution

Step-by-step explanation:

Firstly, let us check if we would be having a real solution

We start by rewriting the equation

We have this as;

8x^2 -25x + 24 = 0

We proceed to get the discriminant

Mathematically, we have this as;

D = b^2 - 4ac

b is the coefficient of x which is -25

a is the coefficient of x^2 which is 8

c is the last number which is 24

So we have;

D = (-25)^2 - 4(8)(24)

D = 625 - 768 = -143

Since the value of the discriminant is negative, there cannot be real roots

What we have as solution are complex roots
