The next statements are are;

Statement                                                  {}        Reason

Segment \overline {DC} ≅ Segment \overline {AB}                        {}   CPCTC

\overline {AD} ≅ \overline {BC} and \overline {DC} ≅ \overline {AB}, therefore;

ABCD is a parallelogram                    {}               Parallelogram side theorem

Step-by-step explanation:

Statement                                                  {}        Reason

Segment \overline {DC} ≅ Segment \overline {AB}  by Congruent Parts of Congruent Triangles are Congruent (CPCTC)

Given that \overline {AD} ≅ \overline {BC} and we have that \overline {DC} ≅ \overline {AB}, we get;

ABCD is a parallelogram                    {}               Parallelogram side theorem

The parallelogram side theorem states that a quadrilateral is a parallelogram if it has two pairs or sets of congruent opposite sides.

b.Three classes will use 3× paint of each class

= 3\times3\frac{1}{2}= 10(1/2) gallons

c. 4 student paint 30 square-foot wall the each student would paint

\frac{30}{4} = 7(1/2) square-foot wall.

d. each student will paint \frac{1}{4} of the wall since there are 4 students.

Please help me figure out this problem
tiny-mole [99]

Answer:

f(g(x))=f\left(-\dfrac{3x+21}{5}\right)=x\\\\g(f(x))=g\left(-\dfrac{5}{3}x-7\right)=x

Step-by-step explanation:

Fill in the given expressions and simplify.

f(g(x))=f\left(-\dfrac{3x+21}{5}\right)=-\dfrac{5}{3}\left(-\dfrac{3x+21}{5}\right)-7\\\\=\left(-\dfrac{5}{3}\right)\left(-\dfrac{3x}{5}\right)-\left(\dfrac{5}{3}\right)\left(-\dfrac{21}{5}\right)-7\\\\=\dfrac{15x}{15}+\dfrac{5\cdot 21}{3\cdot 5}-7=x+7-7=x

Going the other way, we have ...

g(f(x))=\displaystyle -\frac{3\left(-\frac{5}{3}x-7\right)+21}{5}=-\frac{-5x-21+21}{5}=x

Alexis is knitting a blanket 2 meters long. Every 2 decimeters, she changes the color of the yarn to make stripes. How many stri
IgorC [24]

Answer:

There are 10 stripes in the blanket.

Step-by-step explanation:

We are given the following in the question:

Length of blanket = 2 meters

1 meter = 10 decimeter

Length of blanket in decimeter =

2\times 10 = 20\text{ decimeters}

Change of color = Every 2 decimeters.

Number of stripe =

=\dfrac{\text{Length of blanket}}{\text{Length of change of color of stripe}}\\\\=\dfrac{20}{2} = 10

Thus, there are 10 stripes in the blanket.
