Answer: x = 5/2 = 2.5
Step-by-step explanation:
<u>Given expression</u>
2x (x + 3) = 2x² + 15
<u>Expand parentheses and apply the distributive property</u>
2x · x + 2x · 3 = 2x² + 15
2x² + 6x = 2x² + 15
<u>Subtract 2x² on both sides</u>
2x² + 6x - 2x² = 2x² + 15 - 2x²
6x = 15
<u>Divide 6 on both sides</u>
6x / 6 = 15 / 6
x = 15/6
Hope this helps!! :)

Answer:
x=17
Step-by-step explanation:
we know that AD is 90 so you have to subtract 73 to 90
90-73=17 x is a reflection of FD so the value of x is x=17
C. In exactly the same location as B.
This is because they are the same so they have to be in the same place :)
A) tomatoes : chicken broth = 9:15 or 3:5
Tomatoes : spinach = 9:9 = 1:1
Spinach : chicken broth = 9:15 = 3:5
b) tomatoes : chicken broth = 4.5:7.5 = still 3:5
Tomatoes to spinach is still 1:1
Spinach : chicken broth 4.5:7.5 still = 3:5
Dividing all quantities by 2 doesn’t change the ratio.
Step-by-step explanation:
2x - 5 = 1/2*(3x - 13)
4x - 10 = 3x - 13
x = -3
