Answer:
f(-2) =8
Step-by-step explanation:
f(x) = 3x^2+x-2
Let x = -2
f(-2) = 3 * (-2)^2 + (-2) -2
= 3(4) -2 -2
=12 -2-2
=10 -2
=8
A)He can cut 5 strips of of 7/10m.
7/10=0.7m
0.7*5=3.5m
3.5m of wire wil be used in cutting possible 7/10m pieces.
b)Leftover will be 0.6m.
4.1-3.5=0.6m
Answer:
12a + 6
Step-by-step explanation:
given 3(4a + 2)
multiply each term in the parenthesis by the 3 outside ( distributive law )
= (3 × 4a ) + (3 × 2 ) = 12a + 6
So we know if there are 5 groups/dozens of Monarch butterflies, there are 2 groups/dozens of Queen butterflies. In other words, there are 5 Monarch butterflies for every 2 Queen butterflies.
Then we can turn that into an equation.
From the last equation we wrote we can see that the total number of butterflies in the farm is
.
When we compare the Queen butterflies to total butterflies, we get
The ratio of Queen butterflies to total butterflies is 2:7.
I think 22 is 60 idk though but I think
