Komok [63]3 years ago

Answer:

No. In order to be a right triangle, the lengths of the 2 smaller sides must equal the length of the longest side.

In other words, these 3 sides must work with the Pythagorean theorem.

A^2 + B^2 = C^2

25^2 + 30^2 is NOT 30^2

This is a triangle, just not a right triangle.

1. f(x) = 2x + 6 Evaluate f(2)
fredd [130]
1) f(x)=2x+6
f(2)=2(2)+6
=4+6
=10

2)f(x)=3x
f(a+1)=3(a+1)
=3a+3
3)f(x)=3x-1 and g(x)=5x+3

f(2)=3(2)-1
f(2)=6-1
=5
g(3)=5x+3
=5(3)+32
=15+3
=18


f(2)+f(3)=5+18
=23.

Step-by-step explanation:

<u>Lets calculate the points:</u>

  • Art - 2 hrs - B (3)                ⇒ 2*3 = 6 points
  • History - 3 hrs - A (4)         ⇒ 3*4 = 12 points

  • Math - 3 hrs - B (3)            ⇒ 3*3 = 9 points
  • Lab - 1 hr - A (4)                 ⇒ 1*4 = 4 points

<u>Totals</u>

  • Total hours = 13            
  • Total points = 39

<u>GPA = total points/ total hours</u>

  • GPA = 39/13 = 3.0
