Answer:
210 ft^2
Step-by-step explanation:
The area of a triangle is
A = 1/2 bh where b is the base and h is the height

210 ft^2
Answer:
C
Step-by-step explanation:
(3.6xy^5)(2.5x^2y^-2)
9x^3y^3
Answer: x ≥ 11
Step-by-step explanation: We wrote an inequality to represent this situation.
3+1/x *x = 7/x*x
3x+1 = 7
3x+1-1=7-1
3x=6
3x/3 =6/3
x =2
