Answer:

I assume you mean x^2 - 14x + 48. To factor this you want to find a number that adds to -14 and multiplies to 48. That means it'll have to be two negative numbers.

-6*-8 = 48

-6 + (-8) = -14

Your factored expression is (x - 6)(x - 8)

The expression - 340 + 13x represents a submarine that began at a depth of 340 feet below sea
kirill115 [55]

Answer:

A) The submarine was -249  feet below sea level after 7 minutes.

B) The submarine will have reached sea level after 26.15384615384615 minutes.

Step-by-step explanation:

x = 7 minutes

So...

Our equation will be -340 + 13 x 7 =

First, we will solve the multiplication.

13 x 7 = (10 x 7) + (3 x 7) = 70 + 21 = 91.

Then, we solve the addition. -340 + 91 = 340 - 91 = 249

So, the submarine was -249 feet below sea level after 7 minutes.

I don't know how to answer this please help this is urgent.
lukranit [14]

Answer:

V = 240 in ^3

SA = 2(lw+lh+wh)

SA = 236 in^2

Step-by-step explanation:

Volume = l*w*h where l=length, w= width and h =height

We know l=6, w=5 and h =8

V = 6*5*8

V = 240 in ^3

The formula for surface area of a rectangular prism is

SA = 2(lw+lh+wh)  where l=length, w= width and h =height

We know l=6, w=5 and h =8

Substituting into the equation

SA = 2(6*5+6*8+5*8)

     = 2 (30+48+40)

     =2(118)

     = 236 in ^2
