No beacuse 1/4 would be less that 1/2 it's common sense
Answer: 3a-21
Step-by-step explanation:
Apply distributive property
a=3-3*7
Multiply 3*7=21
Answer: 3a--21
The equation of the straight line is y=mx+q where q is the number on the y-axis where the line passes, as you can see it is -3. It turns into:
y=mx+(-3) -> y=mx-3
Then consider a point on the line and take the coordinates, such as the point with coordinates (-2;-4), so now you know that:
x=-2 and y=-4
At this point you put these values into the equation:
y=mx-3
-4=m(-2)-3
then solve:
-4=-2m-3
-2m=+3-4
-2m=-1
m=+1/2
Put the value of m into the equation and you found it:
y=1/2x-3
Answer:

Step-by-step explanation:
First of all, write the equation in standard form. Then identify a, b, c and fill in the values in the formula.

Answer:
Each cm cube has a surface area of 6cm, and it makes 100 mm cubes that have a 6mm surface area each.
