You would do
42=1/2*b*h
you would plug in what you know which is h=5
then you is multiply .5 by 5
which would be 2.5 then you would divide it on both sides of the equal side
42=2.5*b
which then b would stand alone and 42/2.5 is 16.8 which would equal b so your base is 16.8m^2
Answer:
20 feet
Step-by-step explanation:
convert yard to foot
1 yard = 3 foot
7 1/3 x 3 = 22
22 -2 = 20 feet
Answer:
Converting the equation
into completing the square method we get: 
Step-by-step explanation:
we are given quadratic equation: 
And we need to convert it into completing the square method.
Completing the square method is of form: 
Looking at the given equation 
We have a = x
then we have middle term 20x that can be written in form of 2ab So, we have a=x and b=? Multiplying 10 with 2 we get 20 so, we can say that b = 20
So, 20x in form of 2ab can be written as: 2(x)(10)
So, we need to add and subtract (10)^2 on both sides

So, converting the equation
into completing the square method we get: 
Where are the boxes we’re looking at??
Answer: $86.25
Step-by-step explanation:
For this problem, we are given p, r, t.
p=70 (starting amount)
r=0.11 (11%)
t=2 (years)
We can plug this into the equation B=p(1+r)^t
B=70(1+0.11)^2
B=86.247
Sam would have $86.25
