A construction company wants to build an auditorium on a trapezium shaped plot measuring 410m2. One of the parallel sides of the

Assoli18 [71]

Answer:

other parallel side is 23m

Step-by-step explanation:

Let's assume other parallel sides as 'x'

One of the parallel sides of the trapezium plot measure 18m

so, y=18

distance between the two parallel sides measure 20m

so, h=20

now, we can use area of trapezium formula

$A=\frac{1}{2}\times h \times (x+y)$

now, we can plug values

$A=\frac{1}{2}\times 20 \times (x+18)$

we can set A=410

and then we can solve for x

$410=\frac{1}{2}\times 20 \times (x+18)$

$10\left(x+18\right)=410$

$x+18=41$

$x=23$

Solve: 3 = -2v - V V=

Y_Kistochka [10]

Answer:

V = −1

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

3=−2v−v

3=−2v+−v

3=(−2v+−v)(Combine Like Terms)

3=−3v

Step 2: Flip the equation.

−3v=3

Step 3: Divide both sides by -3.

−3v = 3

-3 -3

v=−1
