Its D because the number shaded is 6 and circles 8 that is 6/8 and decimal vesion 0.75 in D there was 3/4 its 0.75 so D is your answer
14a^2 - 24a + 7 - (11a^2 + 42a - 6)...distribute the negative thru the parenthesis
14a^2 - 24a + 7 - 11a^2 - 42a + 6 =
3a^2 -66a + 13 <==
Answer:
Step-by-step explanation:
Lets start by labeling the triangle. Lets say the height is x and the base is x-16.
Next, we know the area of the triangle is 96, so we should make an equation. The area (96) of a triangle is (b*h)/2. So lets substitute.
96=[(x-16)*x]/2
Now, we should simplify the equation. Let us start by moving the /2 to the other side and making it *2.
192=(x-16)*x
Open parenthesis and get
192=x^2-16x
simplify and get
x=24
x is the height so the base must be x-16.
base=8, height=24
Answer: 3x+y=8

Answer:
only 6 brownies had both chocolate and walnuts
Step-by-step explanation:
lets found out how many brownies had walnuts.
90/5= 18
18x3= 54 brownies had walnuts.
_______________________________________________
chocolate brownies.
90/3= 30 brownies had chocolate.
________________________________________
54+ 30= 84 brownies
90-84= 6
