Answer:

(5y^2+2z)(5y^2-2z)

Step-by-step explanation:

Use the difference of squares formula.

a^2-b^2=(a+b)(a-b)

a=5y^2 \\ b=2z

(5y^2+2z)(5y^2-2z)

Isaac keeps track of the miles per gallon his car gets per week. He has accumulated the following data:
ipn [44]

we know that

A <u>geometric sequence</u> is a sequence of numbers in which the ratio between consecutive terms is constant

so

Let

a1=24 \ a2=24.48\ a3=24.97\ a4=25.47

\frac{a2}{a1} = \frac{24.48}{24}= 1.02

a2=a1*1.02

\frac{a3}{a2} = \frac{24.97}{24.48}= 1.02

a3=a2*1.02

\frac{a4}{a3} = \frac{25.47}{24.97}= 1.02

a4=a3*1.02

therefore

The common ratio is equal to 1.02

<u>the answer is</u>

The common ratio is 1.02

The four points (−2, 5), (−2, −1), (6, −1), and (3, 5) are the vertices of a polygon. What is the area, in square units, of this
crimeas [40]
Look at the picture.

The polygon is a right-angled trapezoid.

The area is:
A=\frac{a+b}{2} \times h

The points (-2,-1) and (6,-1) lie on the same horizontal line, so the distance between them is 6-(-2)=6+2=8. The length of a is 8 units.
The points (-2,5) and (3,5) lie on the same horizontal line, so the distance between them is 3-(-2)=3+2=5. The length of b is 5 units.
The points (-2,5) and (-2,-1) lie on the same vertical line, so the distance between them is 5-(-1)=5+1=6. The length of h is 6 units.

A=\frac{8+5}{2} \times 6=\frac{13}{2} \times 6=13 \times 3=39

The area is 39 square units.
