Decide whether the numbers can represent the side lengths of a triangle. If they can, classify the triangle as right, acute, or obtuse.
(pls help me im desperate for an answer for 5, 6, 7, and 8)
Answers
Answer:
4) i) The numbers can represent the side lengths of a triangle
ii) Right triangle
5) i) The numbers can represent the side lengths of a triangle
ii) Isosceles triangle
6) i) The numbers can represent the lengths of the sides of a triangle
ii) Pythagoras theorem
7) The numbers do not represent the lengths of sides of a triangle
8) i) The numbers can represent the side lengths of a triangle
ii) Scalene triangle
Step-by-step explanation:
In a triangle, the sum of the lengths of the two shorter sides is longer than the length of the longest side
The given numbers are;
4) i) 15, 20, 25
Given that 15 + 20 < 25, the numbers can represent the side lengths of a triangle
ii) 15² + 20² = 25²
Therefore, the sides lengths are in line with the side length of a right triangle as their relation is given by Pythagoras theorem
The triangle is a right triangle
5) i) The given numbers are;
2, 6, 6
Given that 2 + 6 > 6, the numbers can represent the side lengths of a triangle
ii) Given that the lengths of two sides are equal (6 each), the triangle formed by the numbers is an isosceles triangle
6) i) 0.27, 0.36, 0.45
0.27 + 0.36 = 0.63 > 0.45, therefore, the numbers can represent the lengths of the sides of a triangle
ii) Given that 0.27² + 0.36² = 0.45², according to Pythagoras theorem, the type of triangle formed is a right triangle
7) 2.5, 1.5, 4
Given that 2.5 + 1.5 = 4, the numbers do not meet the criteria for forming triangles and therefore they cannot represent the side lengths of a triangle
8) i) 12, 16, 25
12 + 16 = 28 > 25, the numbers can represent the side lengths of a triangle
ii) 12² + 16² = 400 < 25² = 625, therefore, the triangle formed by the numbers is not a right triangle but a scalene triangle.

divide both sides by 4

x = 3
x/-3 = 1
multiply both sides by -3
x/-3 (-3) = 1 (-3)
simplify both sides

Answers
Answer:
a
Step-by-step explanation:
[tex]6x+4=20-2x[/tex]
Add 2 to each side
[tex]8x+4=20[/tex]
Subtract 4 from each side
[tex]8x=16[/tex]
Divide 8 by each side
[tex]x=2[/tex]
Answer:
a
Step-by-step explanation:
Your goal is to isolate the variable(x). If you subtract 4 from the left side and right side, then you are left with , 6x=16-2x. Then you add 2x to both sides to get 8x=16. Lastly divide both sides by 8 to get x=2. Hope this helps :)

A business owner wants to have the front window of her store painted and is considering two
artists for the job. Tiana has quoted a flat rate of $292 for the job. Denise's quote is $39 per
hour, plus $19 to cover the cost of materials. Depending on how long it takes Denise to paint
the window, these two could end up charging the same amount. How long would Denise have
to take? How much would it cost?
Answers
to get the answer:
i subtracted $19 from $292 to eliminate the
fee element because if you were to divide
$292 by $39 without the step, the hours would be incorrect and the price would be greater.
after subtracting i got $273
from there i divided $273 by $39 and got 7 (the amount of hours it would take)
Writing a linear equations
Answers
Answer:
y = -4x + 5
Step-by-step explanation:
Equation of the line can be written as y = mx + b (slope-intercept form)
Where m = slope and b = y-intercept of the line.
Let's find m and b of the line
Slope (m) using the points (1, 1) and (0, 5),
Slope (m) = change in y/change in x
m = (5 - 1)/(0 - 1) = 4/-1
m = -4
Find b:
b = the point where the line cuts the y-axis = 5 (y-intercept)
To write the equation substitute m = -4 and b = 5 into y = mx + b
y = -4x + 5

10. C= 5
11. B= 2 V55 (2 square root of 55)
12. C= 2 V5
13. A= V5.39
Explanation:
10. a^2+b^2=c^2
3^2+4^2=c^2
9+16=c^2 (add 9 and 16)
25=c^2
V25= Vc^2 (take the square root of both sides to get):
5=c
11. 6^2+b^2=16^2
36+b^2=256 (256-36)
b^2=220 (square root, 220 cannot be simplified so you factor it and get):
b= 2 V55
12. 4^2+2^2=c^2
16+4=c^2
20=c^2 ( square root it then factor)
2 V5 = c
13. a^2+3.5^2=4.2^2
a^2+12.25=17.64 (subtract 17.64 and 12.25)
a^2=5.39 ( square root/ cannot be simplified so the square root of 5.39 is your answer)

We will use the standard form of a circle to solve for the radius and then fill it back in. h is 0, k is 0, x is 3, and y is 6:
[tex](3-0)^2+(6-0)^2=r^2[/tex] and
[tex]3^2+6^2=r^2[/tex] and
[tex]9+36=r^2[/tex]
Therefore, r-squared is 45, so the circle's equation in standard form is

[tex]\implies x = (-2) \qquad or\qquad x = \dfrac{-3}{2}[/tex]
Step-by-step explanation:
Given :-
A quadratic equation is given to us.The equation is 2x² + 7x +6=0And we need to find out the roots of the given equation. We can use the middle term splitting method to find out the roots as ,
Given equation :-
[tex]\implies 2x^2 + 7x +6=0[/tex]
Step 1: Find out the factors of 12 :-
We will choose the two factors such that their sum equals to the coefficient of x i.e. 7 .The factors are , 1×12 , 2×6 , 3×4 .
And 3 + 4 = 7. So we will break the middle term into 3x and 4x .Step 2 : Breaking the middle term :-
[tex]\implies 2x^2 + 3x+4x +6=0[/tex]
Step 3: Take out common from terms :-
[tex]\implies x(2x + 3) +2(2x +3)=0[/tex]
[tex]\implies ( x +2)(2x+3)=0 [/tex]
Step 4 : Equate them with 0 :-
[tex]\implies x = (-2) \qquad or\qquad x = \dfrac{-3}{2}[/tex]
Hence the correct options are C and D .

what is the missing exponent?
17 / 17^4 = 17^8
Answers
Answer:
The missing exponent is 12.
Step-by-step explanation:
Whenever you divide same-base exponents, you keep the base numbers the same and subtract the exponents.
The only number subtracted by 4 that would give you 8 is 12.
Or, if the numbers are larger, it is must easier to add the exponent in the answer to the number in the equation.
For example,
[tex]17^4+17^8=17^1^2[/tex]
Therefore, the missing exponent is 12.
Because: [tex]17^1^2/17^4=17^8[/tex]
