Answer:
The answer to your question is: x = - 1 / 8
Step-by-step explanation:
8( 1 - 5x ) = 13
8 - 40x = 13
- 40x = 13 - 8
- 40x = 5
x = - 5 / 40
x = - 1 / 8
Answer:
i dont know what it means by expand but i will simplify it
it would simplify to 16x-18
Step-by-step explanation:
5(2x-1) + 2(3x-6)
10x-5+6x-12
10x+6x-5-12
16x-18
Answer:
We know that the area of a square of side length L is given by:
A = L^2
Here, the total area of the white square is:
A = (3x + 1)^2
And the area of the shaded square is:
A' = (2x + 3)^2
a) If we remove the shaded area from the white area, the remaining area is just the difference between the two, then:
area = A - A' = (3x + 1)^2 - (2x + 3)^2
This is the expression we wanted.
b) Now we need to expand and simplify the expression:
area = (3x + 1)^2 - (2x + 3)^2
area = (3x)^2 + 2*(3x)*1 + 1^2 - (2x)^2 - 2*(2x)*3 - 3^2
area = 9x^2 + 6x + 1 - 4x^2 - 12x - 9
area = (9 - 4)*x^2 + (6 - 12)*x + 1 - 9
area = 5*x^2 - 6*x - 8
This is the simplified equation for the remaining area.
Answer:
h= -2/7
Step-by-step explanation:
Simply simplify the equation:
2 = 4 + 7h
first get rid of the 4
2-4 = -2
so -2 = 7h
so h = -2/7
