Your Answer Is....

A) Acute, C) Equilateral, And D) Isosceles. 

Why?

Acute = All Sides Less Than 90°. Equilateral = All Sides The Same. Isosceles = 2 Or 3 Sides The Same. Therefore, A, C, And D Are Your Answers.

Answer:

a and c are correct options.

Step-by-step explanation:

We have been given the triangle 60 60 60

  • Since all the angles are less than 90 degrees hence, the triangle is acute.
  • Apart from these the triangle is an equilateral triangle because an equilateral triangle has all sides equal and hence the interior angles are 60 degrees.
  • The triangle is not right triangle because none of the angle is 90 degrees and also not obtuse since all the angles are less than 90 degrees.
  • Since, the triangle has all sides equal (equilateral triangle) hence it must not be scalene and isosceles.

Therefore, the triangle is (a) acute and (c) equilateral

Answer:

Step-by-step explanation:

a=4    b=12

2a+3b=

2*4+3*12=

8+36=

44

a²-b+10=

4²-12+10=

4*4-2=

16-2=

14

(ab)²-(a+b)²=

(4*12)²-(4+12)²=

48²-16²=

(48+16)(48-16)=

Can someone help me please
Llana [10]

Answer:

8: 50 hours

9: 6 inches

10: 43 cm

Step-by-step explanation:

I couldn't see the entirety of 7 because some of the page was folded, so I didn't answer it.

8: Make them equations of y=12x+450 and y=21x. Since both equal y, set them equal to each other so 21x=12x+450. Subtract 12x from both sides to get 9x=450. Divide by 9 on both sides to get 50.

9: The length equals 3w-6 and the width is just w. The perimeter would equal 2w+2(3w-6) which when factored is 2w+6w-12. Simplify to 8w-12. If P=8w-12 and we know P=36, then set the two equations equal to each other so that 8w-12=36. Add 12 to both sides to get 8w=48. Then divide both sides by 8 to get a final answer of w=6.

10. P=x+5x+8+4x-7. Simplify that to P=10x+1. We know that P=71, so set the two equations equal to each other to get 71=10x+1. Subtract 1 from both sides to get 70=10x. Divide both sides by 10 and x=7. Now substitute x in each side of the triangle and we get 7, (4*7-7), and (5*7+8). Solve all of those to get sides of 7, 21, and 43. The question asks what is the length of the longest side, so the answer would be 43.

Rationalize the denominator and simplify. StartFraction 5 minus StartRoot 3 EndRoot Over 4 plus 2 StartRoot 3 EndRoot EndFractio
nasty-shy [4]

Answer:

\frac{13-7\sqrt{3}}{2}

Step-by-step explanation:

We need to rationalize the denominator of = \frac{5-\sqrt{3}}{4+2\sqrt{3}}. For rationalizing we multiply the equation by \frac{4-2\sqrt{3}}{4-2\sqrt{3}}

So, solving

= \frac{5-\sqrt{3}}{4+2\sqrt{3}}*\frac{4-2\sqrt{3}}{4-2\sqrt{3}} \\=\frac{(5-\sqrt{3})(4-2\sqrt{3})}{4+2\sqrt{3}*4-2\sqrt{3}}\\=\frac{(5-\sqrt{3})(4-2\sqrt{3})}{(4)^2-(2\sqrt{3})^2}\\= \frac{5(4-2\sqrt{3})-\sqrt{3}(4-2\sqrt{3})}{16-(4*3)}\\=\frac{20-10\sqrt{3}-4\sqrt{3}+2*3}{16-12}\\=\frac{20+6-14\sqrt{3}}{4}\\=\frac{26-14\sqrt{3}}{4}\\= \frac{2(13-7\sqrt{3})}{4}\\=\frac{13-7\sqrt{3}}{2}
