Answer:

12

Step-by-step explanation:

The area of a triangle is calculated with the following formula:

\frac{1}{2} *b*h (b: base, h: height (or legs))

We can use this formula to find the length of the other leg:

30 = \frac{1}{2} *b*h multiply both sides with 2 to get rid of fraction

60 = b*h one of the leg's length is given as 5 so

60 = 5*h divide both sides by 5

12 = h is the length of the missing leg.

Answer:1)5x^2-11x

             2) x^2-3x

Step-by-step explanation:

1)(f+g)(x)

f(x)=3x-7

g(x)= 2x-4

[(3x-7)+(2x-4)](x)

3x^2-7x+2x6^2-4x

=<u>5x^2-11x</u>

2) (f-g)(x)

[(3x-7)-(2x-4)](x)

(3x-7-2x+4)(x)

3x^2-7x-2x^2+4x

x^2-3x

(45pts) An elevator holds at most 1,400 pounds. A team of movers and their cart have a combined weight of 1,200 pounds. If each
emmainna [20.7K]
Let x be the number of boxes the team brings with them. Their weight combined with the boxes can't exceed the capacity of 1400. Assuming the elevator runs fine at that exact weight, you want to find the number of boxes, each of which contributes 40 pounds. This is given by the equation

1400=1200+40x

Solving for x, you have

1400=1200-40x
200=40x
x=5

So the team can bring *at most* 5 boxes at a time.
