Answer:

x= 3.25

Step-by-step explanation:

Lets start off by writing the equation: 4x-5=-8

next you subtract 5 from both sides

then you will get: 4x=-13

next you will divide 4 from both sides to isolate x and what is equal to x

then you get your answer :)

4x-5=-8

4x-5=-8\\    -5        -5

4x=-13

\frac{4x=-13}{4}

x = -3.25

i hope this helps luv :)

r=32\,\text{units}\\\\&#10;A=\pi\cdot r^2=\pi\cdot32^2=1024\pi\,\,\text{units}^2

Answer D.

2.
From secant theorem, we know, that:

|AE|\cdot|BE|=|DE|\cdot|CE|

and from picture:

|BE|=x+1\\\\|CE|=x+4\\\\|AE|=11+x+1=x+12\\\\|DE|=1+x+4=x+5

So we can calculate:

|AE|\cdot|BE|=|DE|\cdot|CE|\\\\(x+12)\cdot(x+1)=(x+5)\cdot(x+4)\\\\&#10;x^2+12x+x+12=x^2+5x+4x+20\\\\&#10;x^2+13x+12=x^2+9x+20\quad|-x^2\\\\13x+12=9x+20\quad|-9x\\\\4x+12=20\quad|-12\\\\4x=8\quad|:4\\\\\boxed{x=2}

PLEASE HELP! 20 POINTS AND WILL MARK BRAINLIEST!
lutik1710 [3]

Answer:

210 meters

Step-by-step explanation:

x² + 32500 = 76600

x² = 76600 - 32500

x² = 44100

This already is a perfect square

x = 210

(x is a side, so can't be negative. Therefore only positive square root)
