Find the area of the trapezoid
Sergeeva-Olga [200]

Answer:

44

Step-by-step explanation:

Formula

\frac{1}{2}  \times h \times (sum \: of \: parallel \: sides(b1 + b2))

Your scale is 2cm to 2units therefore the parameters are as follows

h=4

b1=9

b2=13

\frac{1}{2}  \times 4 \times (9 + 13)

\frac{1}{2}  \times 4 \times 22

\frac{1}{2}  \times 88

\frac{88}{2}  \\  = 44

A student concluded that the solution to the equation sqrt2x+1 +3=0 is x=4. Do you agree? Why or why not?
Katyanochek1 [597]

Just put 4 as x in the equation and solve it. The new equation is:

sqrt(2*4)+1+3 = 0

Now we can solve it.

sqrt(2*4) becomes sqrt8:

sqrt8+1+3=0. -------> sqrt8+4=0

The sqrt of 8 is about 2.83.. so 2.83+4 is:

6.83

So we have 6.83 as the answer

but 6.83 does not equal 0 so x cannot equal 4
