Answer:
(f + g)(3) = 9
Step-by-step explanation:
Given:
f(x) = x² + 1
g(x) = x - 4
Required:
(f + g)(3)
SOLUTION:
✔️Find f(3) by substituting x = 3 into f(x) = x² + 1:
f(3) = (3)² + 1 = 9 + 1
f(3) = 10
✔️Find g(3) by substituting x = 3 into g(x) = x - 4:
g(3) = 3 - 4
g(3) = -1
✔️Find (f + g)(3):
(f + g)(3) = f(3) + g(3)
= 10 + (-1)
= 10 - 1
(f + g)(3) = 9
You can split this shape into two shapes; a rectangle on top and a horizontal rectangle underneath. The top rectangle would be 4 x 2 = 8 square units, and the bottom rectangle would be 7 x 1 (3 - 2) = 7 square units. Now you just add these to get 15 square units. I hope this helps!

(engineering notation)
(trillion; prefix tera- (T))
= 7034000000000
(real number)
Step-by-step explanation:
Convert Scientific Notation to a Real Number
Multiply the decimal number by 10 raised to the power indicated.
Examples:
3.456 x 10^4 = 3.456 x 10,000 = 34560
3.456 x 10^-4 = 3.456 x .0001 = 0.0003456
Every two triangles are similar. Therefore the sides of triangles are in proportion.
We have the equations:
1.
<em>cross multiply</em>
<em>divide both sides by 5</em>
<em>subtract 3 from both sides</em>
--------------------------------------
2.
<em>cross multiply</em>
<em>divide both sides by 3</em>
------------------------------------------
3.
<em>cross multiply</em>
<em>divide both sides by 5</em>
<em>subtract 12 from both sides</em>
----------------------------------------------
4.
<em>cross multiply</em>
<em>divide both sides by 3</em>
