Answer:
14 yards
Step-by-step explanation:
the area of a triangle is 0.5×b×h
so
plug in what you have
0.5×b×3=21
(3x0.5)b=21
1.5b=21
b=21/1.5
b=14
Answer:
the answer is 64 im 100% sure
The simplified form of this equation is 5^3.
You simplify these types of equations by adding/subtracting the exponents, since there is multiplication/division and the constant is the same throughout.
Answer:

Step-by-step explanation:
We can let the
be
. Rewriting the proportion, we get:

Solving for
, we get:

(Cross-Products Property)
(Simplify)
(Divide both sides of the equation by
to get rid of
's coefficient)
(Simplify)
Since
, we know that
