Answer:
????
Step-by-step explanation:
Answer:
The base is 11 cm.
Step-by-step explanation:
The formula for the area of a triangle is . If we plug in what we know to this equation, we are left with , which we now need to simplify.
First, we combine like terms.
Then, we can eliminate the and on the right side of the equation, since they cancel each other out.
Finally, we take the square root of both sides of the equation and find our answer:
Answer: 4.6 (rounded to the nearest tenth)
Step-by-step explanation:
I assume that 1.6 is the coefficient of x, which is what we're trying to find out in this case.
Therefore, dividing 1.6 on both sides we get
from
1.6x = 7.37
to
x = 7.37/1.6 = 4.6 (approximately, rounded to the nearest tenth).
