Step-by-step explanation:
25r²-100=0
25r^2 = 100
cuz the (-) will turn (+) when taken to the other side of the (=) sign
25r^2 = 100
<em>divide both sides by 25</em>
<em>divide both sides by 25 then we get </em>
r^2 = 4
r^2 = 2^2
<em>now take the sqare roo</em><em>t</em><em> of both sides</em>
r = 2
If x=8 {f(8)=3x+4}, the answer is 28.
Comment the correct answer.
Original and bigger prism are similar with scale factor k = 4, so:
new surface area = k² * original surface area = 4² * 228 = 16 * 228 = 3648 m²
and
new volume = k³ * original volume = 4³ * 216 = 64 * 216 = 13824 m³
