Rewrite in simplest terms: (9x+5)-(-2x+10)(9x+5)−(−2x+10)

Blababa [14]

$\implies {\blue {\boxed {\boxed {\purple {\sf { 18 {x}^{2} - 69x - 55}}}}}}$

$\large\mathfrak{{\pmb{\underline{\orange{Step-by-step\:explanation}}{\orange{:}}}}}$

$= (9x + 5) - ( - 2 x+ 10)(9x + 5) - ( - 2x + 10)$

$= (9x + 5) + 2x (9x + 5) - 10(9x + 5) - ( - 2x + 10)$

$= 9x + 5 + 18 {x}^{2} + 10 x- 90x - 50 + 2x - 10$

Collect the like terms.

$= 18 {x}^{2} + (9x + 10x- 90x + 2x) + (5 - 50 - 10)$

$= 18 {x}^{2} + (21x - 90x) +(5 - 60)$

$= 18 {x}^{2} - 69x - 55$

What the answer now to the question

Lostsunrise [7]

Step-by-step explanation:

Hello!!!

Given, VXW is a Right angled triangle where WV =4 and XV =5.

now, by taking reference angle as angle W, and using tangent we get;

p=5

b=4

again, 

tan thita =p/b

tan thita = 5/4

so, tan thita =1.25.

now, to find angle W, we should do tan thita inverse;

or, (tan thita)-1= tan thita-1(1.25)

or, (tan thita) -1 =51.3401°.

Now, by rounding off we get,

tan thita (angle W )= 51°.

Hope it helps....

Please please help please

liq [111]

Answer:

Step-by-step explanation:

Since ,

Wire of Length 36 cm is bent to form a square so,

perimeter of the square = Length of the wire

Hence, perimeter of the square = 36cm

Therefore, one side of the square = 36 cm ÷ 4

= 9 cm

So area of the square = side × side = 9 cm × 9cm

$81 {cm}^{2}$
