D. 
; 
Step-by-step explanation:
We know that the cost of preschool is $ 45 per day plus a monthly fee of $ 70.
We also know that a total of $ 880 was paid last month
To write an equation that represents this situation, let us call "d" the number of days that Barry attends school
So the cost was:
Now we solve the equation for the variable d
Therefore answer is the option D
Answer:
90ft2
Step-by-step explanation:
rectangle= BH
Triangle= BH/2
add em together and you get you're answer
(B is base and H is height)
The unknown number is 1/2 or 0.5.
ex: 4x+6=8
Arrange your given equation to resembles the form
a^2 +2ab+ b^2 because this equals (a+b)^2
So we get:
y^2+16y+8^2=0
Now compare
y^2+16y+8^2 to a^2 +2ab+ b^2
So we got
y^2+2•8 y+8^2=0 which equals (y+8)^2
Answer: 5.8
2+0+3+0+4= 9
9/5 = 5.8
Hope this helps. :)
