Solve for the inequality? A OR B?

Mathematics

1 answer:

ASHA 777 [7]2 years ago

6 0

Step-by-step explanation:

3x - x = 2x

2(x + 2) = 2x + 2

for every number of x, 2x + 2 would always be larger than 2x.

so there is no solution, since the given equation is 2x is greater than 2x + 2.

If x is not equal to 0 then u/x + 5u/x - u/5x = what?

gavmur [86]

$\frac{u}{x}+\frac{5u}{x}-\frac{u}{5x}=\frac{5u}{5x}+\frac{25u}{5x}-\frac{u}{5x}=\frac{5u+25u-u}{5x}=\frac{29u}{5x}$

. CDEF is a trapezium

guajiro [1.7K]

9514 1404 393

Answer:

24 cm²

Step-by-step explanation:

To find the area of the trapezium, we must know the length CD. That means we must know the length BC. Fortunately, the perimeter of ABCF is given, so we have ...

P = 2(AB +BC)

BC = (P/2) -AB = (20 cm)/2 - 6 cm = 4 cm

Then CD is ...

CD = BD -BC = 9 cm -4 cm = 5 cm

The area of the trapezium is given by the formula ...

A = (1/2)(b1 +b2)h

A = (1/2)(5 cm + 3 cm)(6 cm) = 24 cm²

The area of trapezium CDEF is 24 cm².
