She gets 100 miles out of 2 gallons of gas so that means she gets 50 miles per gallon of gas in her hybrid car the unit rate represents Miles per gallon of her car
Answer:
Perimeter of is .
Explanation:
Given: In , , and AD= 8cm.
In
Sum of the measure of the angles of triangles is 180 degree.
or
Simplify:
∵ AD= 8cm and to calculate the length of CD we use tangent ratio i.e,
then;
or
Simplify:
cm.
Also, find the length of AC, we use sine ratio i.e, .
Then,
or
On simplify:
cm.
Now, in triangle ABC;
, then
[Sum of the measure of the angles in the triangle is 180 degree]
To calculate the length of BC;
[∴ ]
therefore,
or
Simplify:
cm.
Using Pythagoras theorem in triangle ACB;
Let BD be x cm
AB = 8+x cm , AC = 16 cm and cm
or
or
Simplify:
x=24 cm
Therefore, the length of AB = 8+x= 8+24=32 cm
Perimeter(P) of triangle ABC is equal to the sum of the sides of the triangle.
⇒ P= AB+BC+AC = cm
The answer is x².
f(x) = <span>5x - 6
</span>g(x) = x²<span> - 5x + 6
(f + g)(x) = f(x) + g(x)
= </span>5x - 6 + x² - 5x + 6
= x² + 5x - 5x + 6 - 6
= x² + 0 + 0
= x²
Answer:
yes
