vredina [299]

Answer:

$\boxed{ \bold{ \huge{ \boxed{ \sf{4 {x}^{3} + 6 {y}^{2} }}}}}$

Step-by-step explanation:

$\sf{5 {y }^{2} + 5 - 4 - 4 {y}^{2} + 5 {y}^{2} - 4 {x}^{3} - 1}$

Collect like terms

⇒ $\sf{ 4 {x}^{3} + 5 {y}^{2} - 4 {y}^{2} + 5 {y}^{2} + 5 - 4 - 1}$

⇒ $\sf{4 {x}^{3} + {y}^{2} + 5 {y}^{2} + 5 - 4 - 1}$

⇒ $\sf{4 {x}^{3} + 6 {y}^{2} + 5 - 4 - 1}$

Calculate

⇒ $\sf{4 {x}^{3} + 6 {y}^{2} + 1 - 1}$

⇒ $\sf{4 {x}^{3} + 6 {y}^{2} }$

Hope I helped!

Best regards! :D

Find the distance between the points given. (2, 2) and (5, 5)

mario62 [17]

Distance between two points, d, is given by
$d= \sqrt{ ( x_{2} - x_{1}) ^{2} + (y_{2} - y_{1}) ^{2} }
$
where: (x1, y1) = (2, 2) and (x2, y2) = (5, 5)
$d= 
\sqrt{ ( 5 - 2) ^{2} + (5 - 2) ^{2} } \\ d= \sqrt{ (3)^{2} + 3^{2} } 
\\ d= \sqrt{9+9} \\ d= \sqrt{18} \\ d=3\sqrt{2} \ units$
