3/4=8/x-1
3/4+4/4=8/x
7/4=8/x
7x/4=8
7x=32
x=32/7
The formula to find the volume multiplies the length by the width by the height.A cube has all edges the same length .If we multiply the edges three times we get the volume of any cube.
Volume of cube with sides a is Volume V= 
In the question the cube is having an edge of 3.4 meters
Volume V= 
Volume of cube is 39.3 cubic meters.
Answer:
17x and 3x
Step-by-step explanation:
like terms are terms that have the same variables and powers. The coefficients do not need to match. Unlike terms are two or more terms that are not like terms, i.e. they do not have the same variables or powers. The order of the variables does not matter unless there is a power.
Answer:
True
Step-by-step explanation:
Here, we want to check if the given equation does not intersect the x-axis
if it does not, then it has no real root
If the discriminant is less than zero, then it has no real roots and does not intersect the x-axis
The formula for the discriminant is;
D = b^2-4ac
In the question;
a = -1 , b = 6 , c = 10
so;
D = 6^2-4(-1)(10)
D = 36-40
D = -4
Since discriminant is less than zero, then there is no real root and the graph does not cross the x-axis
