Answer: 120
Step-by-step explanation:
first you distribute 5 to 11 and -17 to get (55 - 85) then you distribute 6 to 14 and -7 to now get (55-85) + (84-42) then you distribute -12 to 2 and 7 to now have (55-85) + (84-42) - ( -24 + -84) to get 120 you multiple when you distruibute for these cause its outside the parenthesis so you multiply the number by everything in the parenthesis

Find the area of the triangle (white)
Answers
Step-by-step explanation:
something is missing here.
it is not clear, what exactly is 27 km. only the side of the orange triangle ? or the whole distance to the 90 degree angle ?
but in both cases that is not enough. we need some information about the split ratio of the orange side and the white side. it some angles in the graphic.
otherwise I can simply keep the given sides with their lengths but freely move the line between the orange and white triangles. there are infinite many solutions.
is it meant to be an isoceles triangle (2 equal sides) ? it certainly does not look like it, but that would be the only case where the given information can lead to a solution.
under that assumption the baseline of the white triangle is also 27 km.
the first side is 9km.
the second side we get via Pythagoras :
27² = 9² + x²
729 = 81 + x²
648 = x²
x = 25.46 km
now, since this is a right-angled triangle we can (especially to calculate the area) also consider the two sides enclosing the 90 degree angle as baseline and height.
the area of a triangle is baseline×height/2
area = 9×25.46/2 = 114.55 km²

Answer:
∠ V = 58°
Step-by-step explanation:
The sum of the 3 angles in a triangle = 180° , then
∠ WYX = 180° - (52 + 24)° = 180° - 76° = 104°
∠ VYU = ∠ WYX = 104° ( vertically opposite angles )
Then
∠ V = 180° - (104 + 18)° = 180° - 122° = 58°
find the missing side of the triangle.

Answers
Answer:
C. no real number solutions
Step-by-step explanation:
Subtract 10 from both sides.
Since the square of a number, x, equals a negative number, -1, the answer cannot be a real number because the square of a real number is always non-negative. Therefore, there is no real number solution to this equation.
Answer: B. no real number solutions

What is the value of m in the diagram?
Answers
Answer:
81
Step-by-step explanation:
The angles shown are formed on a straight line
Angles formed on a straight line add up to 180
So m + m + 18 = 180
We've just created an equation that we can use to solve for m
So we can now solve for m
m + m + 18 = 180
Combine like terms
2m + 18 = 180
Subtract 18 from both sides
2m + 18 - 18 = 180 - 18
2m = 162
Divide both sides by 2
2m/2 = 162/2
m = 81
Determine the sum of the first 33 terms of the following series:
−52+(−46)+(−40)+...
Answers
Answer:
1320
Step-by-step explanation:
Use the formula for sum of series, s(a) = n/2(2a + (n-1)d)
The terms increase by 6, so d is 6
a is the first term, -56
n is the terms you want to find, 33
Plug in the numbers, 33/2 (2(-56)+(32)6)
Simplify into 33(80)/2 and you get 1320

Answer:
x = -3/2
Step-by-step explanation:
The zeros of the function are the values of x that make the factors zero:
x = -4, x = 1
The axis of symmetry is the vertical line halfway between these zeros.
x = (-4 +1)/2 = -3/2
The equation of the axis of symmetry is x = -3/2.
Solve for x.

When it is dry, he cut the cube into 8 smaller pieces of smaller size. How much paint additional paint does Pinocchio need to paint the unpainted surfaces of the smaller cubes
Answers
Answer:
9 grams of paint
Step-by-step explanation:
6×8=48
48÷4= 12
48-12=36
36÷4=9
first multiply 6 by 8 because a cube has six faces and you cut that cube eight times
second after you cut that you will have 48 faces and for every six faces there are 4 grams of paint so you divide 48 by 4 and you get 12 this means that 12 of the faces are painted
next you subtract 12 from 48 and you get 36 this means that 36 faces are not painted
lastly you divide 36 by 4 and you will get 9 grams of paint

A triangle's angles add up to 180°, and a straight line is 180 degrees, so 180 - x + 31 is the interior angle that isn't labeled.

Total mass = 8 kg
Mass of tool 1 = 4 kg
Mass of tool 2 = 2 kg
So,
Total mass = Mass of tool 1 + Mass of tool 2 + Mass of tool 3
=> 8 kg = 4 kg + 2 kg + Mass of tool 3
=> 8 kg = 6 kg + Mass of tool 3
=> 8 kg - 6 kg = Mass of tool 3
=> 2 kg = Mass of tool 3
