Help me please I'm struggling ​

Step-by-step explanation:

1.

2.

cosθ+sinθ tan θ

=cosθ+sin θ×(sinθ)/(cosθ)

3.

x²+(y-6)²=35

x²+y²-12y+36=35

x²+y²-12y+1=0

put x=r cosθ

y=r sin θ

square and add

x²+y²=r²cos²θ +r² sin²θ=r² (cos² θ+sin² θ)=r²

r²-12rsinθ+1=0

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.

i believe your answer is 99.7% of 7-year-old children are between 46.6 inches and 49.5 inches tall.
