Area of a triangle = 1/2 b•h
A = 1/2 b • h
A = 1/2 (10 cm • 9 cm)
A = 1/2 (90 cm^2)
A = 45 cm^2.
Answer:
2a+7b+18
Step-by-step explanation:
combine the like terms
Answer:
a is 11
Step-by-step explanation:
4+2(5)+-3 is ll
D = 1/2 a t^2 is given. And it wants you to find t in terms if a and d. Which means, you need to arrange the equation and let t be alone.
If you let t^2 alone ;
2d/a = t^2
And square root t^2 will give you t ;
SquareRoot(2d/a) = t
The answer is (2)
7+x is the awnser
unless you meant to type “A number is more than 7” then it would be x>7
