frosja888 [35]

Answer:

a square backyard with width (x - 9)

Step-by-step explanation:

x²−18x + 81 = x² - (2 x 9) x + 9² = (x - 9)²

width = area / length = (x - 9)² / (x - 9) = x - 9

Length = width

This is a square backyard

Another for solving for x but much harder
gulaghasi [49]
Set up the equation so m<HCB + m<DCH = m<DCB

2x + 100 + 60 = x + 170
2x+ 160 = x +170
-x             -x
x + 160 = 170
   - 160     -160
x = 10

MATH!!! find the volume of the pyramid. pleaseee answer correctly and tell me how you got your answer.
bagirrra123 [75]

The area of polygons formulas to V=2.56m^2

We have to determine,

The volume of the pyramid.

<h3>What is the volume of the pyramid?</h3>

The volume of a pyramid is found using the formula,

V = (1/3) Bh

where 'B' is the base area and 'h' is the height of the pyramid.

hight =2.4m

base=1.4+1.8

base=3.2m

V = (1/3) (3.2)(2.4)

V=2.56m^2

As we know the base of a pyramid is any polygon,

we can apply the area of polygons formulas to find 'B.

V=2.56m^2.

Write 4^3 – 6x + 2^5 + 3 in standard form please
lara31 [8.8K]

Answer:

2^5 + 4^3 – 6x + 3

Step-by-step explanation:

Order the numbers by decreasing exponents. Start with the 2^5, since it has an exponent of 5. Next is the 4^3 since it has an exponent of 3. After that is -6x since it has an exponent of 1. 3 is last because it has an exponent of 1 and it has no variables attached.
