Answer:
It depends of what the equation is...
Step-by-step explanation:
If your equation is 3x2 (3x times 2) then the solution would be:
3(4)(2) + 5(2)= 34
If your equation is 3x + 2 + 5y, then the solution would be:
3(4) + 2 + 5(2) =24
The answer is
4a-6b, which can also be written 2(2a-3b).
Hope this helps!
Answer:
15
Step-by-step explanation:
Calculation for What is a reasonable estimate of the number of gallons of gas Karl used
Estimated number of gallons used=619.5 miles/41 miles
Estimated number of gallons used=15
Therefore the reasonable estimate of the number of gallons of gas Karl used is 15
All sides of an equilateral triangle are equal, so all three sides are 9 cm.
To find h, use the pythagorean theorem. This requires use of only one right triangle, where we use b as our h.
a^2+b^2=c^2
(4.5)^2+b^2=(9)^2
(20.25)+b^2=(81)
b^2=(81/20.25) or 4
square root both sides
b=2
