Answer:
Factoring the term we get
Step-by-step explanation:
We need to solve the polynomial:
First we see that 3 is common term, so taking 3 as common
We know that 25 = 5x5 = 5²
So, replacing 25 with 5²
We know that,
Applying this in our equation:
So, factoring the term we get
Answer:
648cm2
Step-by-step explanation:
2(1/2×12×24)+3(12×10)
=288+360
=648 cm2
2x^3+2x^2-x-10

Answer:
x = $3.50; y = $2.25
Step-by-step explanation:
First, come up with your two equations where x= price of walnuts and y= price of chocolate chips: 8x + 4y = 37 and 3x + 2y = 15. Solve the first equation.
3x + 2y = 15
3x = 15 - 2y
x = (15 - 2y)/3
Plug in the answer to your second equation.
8(15 - 2y)/3 + 4y = 37
(120 - 16y)/3 + 4y = 37
120 - 16y + 12y = 111
120 - 4y = 111
-4y = -9
y = 2.25
Plug in your answer to find <em>x.</em>
3x + 2(2.25) = 15
3x + 4.5 = 15
3x = 10.5
x = 3.5
Check your equation.
1) 3(3.5) + 2(2.25) = 15
10.5 + 4.5 = 15
15 = 15
2) 8(3.5) + 4(2.25) = 37
28 + 9 = 37
37 = 37
