Answer:
15ab
Step-by-step explanation:
When you multiply out the square (p+q)^2, you get the trinomial ...
(p +q)^2 = p^2 + 2pq + q^2
Your binomial is (3a+2.5b), so you have ...
p = 3a
q = 2.5b
and the trinomial you get when you multiply it out is ...
(3a)^2 + 2(3a)(2.5b) + (2.5b)^2
= 9a^2 + 15ab + 6.25b^2
The first and last of these terms are shown on the right side of the given expression, so to finish out the identity, you need to replace * with 15ab.
Answer:
20
Step-by-step explanation:
1kg = 1000g
1000×4=4000
4000÷200=20
The average rate of change of f(x) on the interval [a,b] is f(b)−f(a)b−a.
We have that a=1254, b=6103100, f(x)=20(54)x.
Thus, f(b)−f(a)b−a=20(54)(6103100)−(20(54)(1254))6103100−(1254)=−58207660913467407226562517167001203595951472642–√5–√4+542101086242752217003726400434970855712890625197922048572373973475376871275743307366424750⋅53100.

Answer=875miles 17.5miles per gallon
350miles x miles
________=_________
20gallons 50gallons
cross multiply
20x=17500
divide both sides by 20
x=875
875 miles can be traveled with 50 gallons of gas.
To find gas milage, which is essentially miles per gallon, simply divide the number of miles by the number of gallons
350miles 20gallons
350/20=17.5 miles per gallon
Answer:
gradient = 
Step-by-step explanation:
calculate the gradient m using the gradient formula
m = 
with (x₁, y₁ ) = (- 6, 0) and (x₂, y₂ ) = (0, 2) ← 2 points on the line
m =
