Answer:
Step-by-step explanation:
The ratio is 12/8 or 3/2
So we can use proportions
3/2=x/15
x=22.5
I believe you are expected to simplify. To do this all you do is group like terms (x, x², x³ etc.) and then simplify the coefficients.
13. 10z + 7z - 19z² - 5z² - 17z
first you can rearrange and group like terms (remember the bring the sign in front of each term with it). I would do it like this:
-19z² - 5z² +10z + 7z - 17z
Now simplify the coefficients:
-24z² + 0z
you can omit the 0z and your simplified answer is
-24z²
Main thing to remember here is that z and z² cannot be simplified together, nor can any variable that has an exponent because the exponent makes them differ.
Answer:
B. 96 units
Step-by-step explanation:
DA is 6 units and HE is 36 units. There are the same side, but HE is 6 times larger.
AB is 16 units, but since all the sides on the left shape are 6 times larger, EF has to be 16*6, which is 96 units.
