Answer:
26320
Step-by-step explanation:
The CN Tower is 553.33 m (1,815.4 ft) tall from its antenna spire. Meanwhile, the Eiffel Tower only measures 324.00 m (1,063 ft) from its antenna spire.
Since x = y + 2
so
y + 2 + 4y = 7
5y + 2 = 7
5y = 7-2
5y = 5
y = 1
x= y + 2
x = (1) + 2
x = 3
(x,y) = (3,1)
Use the std eqn of a circle with center at (h,k) and radius r:
(x-0)^2 + (y+2)^2 = 9^2, or just x^2 + (y+2)^2 = 9^2.
<em>Answer:</em>
<em><u>X = 80</u></em>
<em>Step-by-step explanation:</em>
<em>Subtract </em><em>"5"</em><em> from both sides,</em>
<em>3x + 5 - 5 = 245 - 5</em>
<em><u>Simplify,</u></em>
<em>3x = 240</em>
<em><u>Divide both sides by </u></em><em><u>"3"</u></em><em><u>,</u></em>
<em>3x/3 = 240/3</em>
<em>X = </em><em>80</em>
<u><em>Hope this helps :-)</em></u>
