Answer:

440 square inches.

Explanation:

We can consider the boxes as one single shape.

So it's base area is 12×10=120 and the area of the side faces is 20×12=240 and 20×10=200.

Now, there are 2 of each, so let's add up everything and multiply by 2.

(120+240+200)×3=560 square inches.

But we have to take off the base, so:

560-120=440 square inches

Tom plants 3 seeds.

Rasek [7]

Answer:

A. 64/125

B. 124/125.

Step-by-step explanation:

A). As the events ( germinate or not germinate) are independent we multiply the probabilities.

Prob(All seeds germinate) = 4/5*4/5*4/5 = 64/125.

B). Probability of at least one germinating = 1 - probability that none germinate

Probability of 1 seed not germinating = 1 -45 = 1/5.

So Prob(at least one germinating)

= 1 - (1/5 * 1/5 * 1/5)

= 1 - 1/125

= 124/125.

Multiply (x-6)(4x + 3) A. 47-32-18 B. 4) - 24%-18 C. 47 - 21%-18 D. 4/2 - 18

PilotLPTM [1.2K]

Answer:

4x² - 21x - 18

Step-by-step explanation:

Use FOIL.

$(x-6)(4x+3)\\\\x*4x = 4x^2\\\\x * 3 = 3x\\\\-6 * 4x= -24x\\\\-6 * 3 = -18\\\\\\4x^2+3x-24x-18\\\\\boxed{4x^2-21x-18}$

Hope this helps.

The function f(x) = x2 + 10x – 3 written in vertex form is f(x) = (x + 5)2 – 28. What are the coordinates of the vertex?

Alexxandr [17]

Vertex form uses the following formula:

$y = a(x-h)^2 + k$

Identify the values of h and k in your function:

$(x+5)^2 - 28$
$h = -5, k = -28$

The vertex is found with the following point:

$(h,k)$
$\text{Vertex: (-5, -28)}$

The vertex will be found at (-5, -28).
