Answer:

x=3

Step-by-step explanation:

x^2 = 6x - 9

Subtract 6x from each side

x^2 -6x = -9

Add 9 to each side

x^2 -6x+9 = 0

Factor

what 2 numbers multiply to 9 and add to -6

-3*-3 = 9

-3+-3 =-6

(x-3)(x-3) = 0

Using the zero product property

x-3 =0 x-3=0

x=3 with multiplicity 2

The statue of liberty is 305 feet tall. A nearby building is 4/9 as tall. Find the height of the building.

inysia [295]

Answer:

The nearby building is $135 \dfrac{5}{9}$ feet tall.

Step-by-step explanation:

The statue of liberty is 305 feet tall.

A nearby building is $\dfrac{4}{9}$ as tall as the statue of liberty.

To find the height of the building, you need to find $\dfrac{4}{9}$ of 305:

$\dfrac{4}{9}\cdot 305=\dfrac{1,220}{9}= 135 \dfrac{5}{9}\ feet$

Thus, the nearby building is $135 \dfrac{5}{9}$ feet tall.

42. The diagram represents a ramp in the shape of a right triangle and the lengths

oee [108]

The length of the ramp is 61 feet.

<h3>What is the length of the ramp?</h3>

In order to determine the length of the ramp, Pythagoras theorem would be used.

The Pythagoras theorem: a² + b² = c²

where a = length

b = base

c = hypotenuse

√11² + 60²

√121 + 3600

√3721

= 61 feet

Please find attached the image of the ramp. To learn more about Pythagoras theorem, please check: brainly.com/question/14580675

Simplify the expression (3 - 4i)(1 + 5i) - (2 - i). Show your work please! I have the answer: 21 + `12i but I need to show my wo

masha68 [24]

Answer:

21+12i i hope this will help you

Step-by-step explanation:

(3-4i)(1+5i)-(2-i)

=[3(1+5i)-4i(1+5i)]-(2-i)

=[3+15i-4i-20i²]-(2-i)

=(3+11i-20i²)-(2-i)

opening brackeys

=3+11i-20i²-2+i

=3+11i+1i-20i²-2

as we know that i²=-1

=3-20(-1)-2+12i

=3+20-2+12i

=21+12i
