Answer:
x = - 0.23 or -(3/13)
Step-by-step explanation:
Question: x+3/-6 =2x
x + 3 = - 6 * 2x
x + 3 = -12x
3 = -12x - x
3 = -13x
x = - 3/13
Answer:
If:
(1)
And we have to rewrite the following expresion in terms of
:
(2)
Firstly we have to rearrange the right side of equation (2) in terms of
, factorizing by the common factor:
Then, we can substitute
by
:
And set it equal to zero:
>>>>This is the resulting equation
Now, each term of an algebraic expresion (like the equation above) is composed of sign, coefficient, variable and exponent. The terms are separated from each other by the plus sign (+) or the minus sign (-).
In this case, the variable is
and the number that multiplies the variable (the coefficient) is
, whereas the constant (which is the term with no variable) is 
Answer:
x = 7√2/3
decimal = 3.299831
Step-by-step explanation:
Subtract 1 from both sides
3√2x+1-1=15-1
Simplify
3√2x=14
Divide both sides by 3√2
3√2x/3√2 = 14/3√2
Simplify
x= 7√2/3
Answer:
37.5 square units
Step-by-step explanation:
Given:
A(-6,-4), B(6,5), C(-1,6), and D(2, 2), where CD is the altitude if ∆ABC
Required:
Area of ∆ABC
SOLUTION:
Area of a ∆ABC =½*AB*CD
✍️



✍️



✍️Area of a ∆ABC =½*AB*CD
= ½*15*5
✅ Area = 37.5 square units

Answer: 9 inches (choice D)</h3>
Work Shown:
V = volume of pyramid
V = (1/3)*(area of base)*(height)
V = (1/3)*(12*10)*h
V = (1/3)*120h
V = 40h
Set this equal to the given pyramid volume 360 cubic inches and solve for h
40h = 360
h = 360/40
h = 9
