evaluate the following expression for x=-2 -4x+8+2x+3

Answer:

Its 67.9 but technically its 67.912 *hope this helps

Step-by-step explanation:

Right scalene triangle.

Sides: a = 66   b = 16   c = 67.912

Area: T = 528

Perimeter: p = 149.912

Semiperimeter: s = 74.956

Angle ∠ A = α = 76.373° = 76°22'23″ = 1.333 rad

Angle ∠ B = β = 13.627° = 13°37'37″ = 0.238 rad

Angle ∠ C = γ = 90° = 1.571 rad

Height: ha = 16

Height: hb = 66

Height: hc = 15.55

Median: ma = 36.674

Median: mb = 66.483

Median: mc = 33.956

Inradius: r = 7.044

Circumradius: R = 33.956

Vertex coordinates: A[67.912; 0] B[0; 0] C[64.142; 15.55]

Centroid: CG[44.018; 5.183]

Coordinates of the circumscribed circle: U[33.956; 0]

Coordinates of the inscribed circle: I[58.956; 7.044]

Exterior (or external, outer) angles of the triangle:

∠ A' = α' = 103.627° = 103°37'37″ = 1.333 rad

∠ B' = β' = 166.373° = 166°22'23″ = 0.238 rad

∠ C' = γ' = 90° = 1.571 rad

Answer:

negative square root will result in zero x-intercepts

Step-by-step explanation:

there are no x-intercepts because if you use the quadratic formula on the equation you get a negative square root which results in zero x-intercepts

in this case, a=-1, b=4, c=-12

[-4±√4² - 4(-1)(-12)] / 2(-1)

= [-4 ± √16-48] / -2

= -4 ± √-32 / -2

Answer:

2000pi

Step-by-step explanation:

V of a cylinder = Area of the base × height

Area of a circle = pi × r^2

A = pi × (10)^2 = 100pi

V = 100pi × 20 = 2000pi

Answer:

A':A = 1742:7

Step-by-step explanation:

Applying,

A' = L'W'............... Equation 1

Where A' = Area of the window, L' = Length of the window, W' = Width of the window.

From the question,

Given: L' = 312 ft, W' = 134 ft

A' = (312×134)

A' = 41808 ft²

Similarly,

A = LW.................. Equation 2

Where A = Area of the image of the window, L and W is thw length and width of the image of the window

Given: L = 12 ft, W = 14 ft

Therefore,

A = 12×14

A = 168 ft²

Therefore the ratio of A' to A = 41808:168 = 1742:7

A':A = 1742:7

Answer:

Finance per billing cycle = $ 30.91

Step-by-step explanation:

First, we will calculate the APR for 1 day:

APR per day = (22.99%/year)(1 year/12 month)(1 month/31 days)

APR per day = 0.062 % / day

Now, we will calculate the finance per day:

Finance per day = (Daily Balance)(APR per day) = ($ 1608.24)(0.062 %/day)

Finance per day = $0.99/day

Now, we will calculate the finance for one billing cycle:

Finance per billing cycle = (Finance per day)(31 days) = ($ 0.99/ day)(31 days)

Finance per billing cycle = $ 30.91

Answer:

Solution given:

[tex] \frac{5 + x}{2} = 4 [/tex]

multiplying both side by 2

[tex] 5 + x = 4 \times 2 [/tex]

subtracting both side by 5

we get

x = 8 -5

x = 3

x = 3is a required answer.

d = 12.25

Step-by-step explanation:

d = √(x2 - x1)^2 + (y2 - y1)^2 + (z2 - z1)^2

P1(0, 0, 0) P2(-1, 7, -10)

Substitute the values in the above equation and you will get

d = √(-1 - 0)^2 + (7 - 0)^2 + (-10 - 0)^2

= √(1 + 49 + 100)

= √150

= 12.25

Answer:

Length of straw = 11 inch (Approx.)

Step-by-step explanation:

Given:

Length of cuboid = 9 inch

Width of cuboid = 5 inch

Height of cuboid = 4 inch

Find;

Length of straw

Computation:

Length of straw = Diagonal of cuboid

Diagonal of cuboid = √l² + b² + h²

Diagonal of cuboid = √9² + 5² + 4²

Diagonal of cuboid = √81 + 25 + 16

Diagonal of cuboid = √122

Diagonal of cuboid = 11.04

Length of straw = 11 inch (Approx.)

Answer:

Answer:

17 meters

Step-by-step explanation:

The perimeter is the addition of all sides. Since the perimeter is 68 meters and a square has 4 sides, we can divide 68 by 4 and we get 17.

Answer:

Step-by-step explanation:

b/c it's square we know all 4 sides are the same length

68 /4 = 17

each side is 17 meters

Answer:

2 2/3 projects

Step-by-step explanation:

First disect the statement.

2/3 of a project in 1/4 of an hour.

This means that she does not completely finish grading a project in a quarter hour.

We want to know how much she gets done in one whole hour, however all we know is how much she gets done in 1/4 of that time. Luckily, 1/4 times 4 is a whole hour. Since 2/3 of a project gets done in 1/4 that means if we multiply 2/3 by four we should also get how much she completes in one hour.

2/3 x 4 = 8/3

8/3 = 2 2/3 projects

You can also right these as ratios:

(2/3)/(1/4) = x/1

x = 8/3

Answer:

x=37

Step-by-step explanation:

Complementary angles are a set of 2 angles that when added together, add up to 90. In order to solve for x, both angles have to be added and set to be equal to 90... but Jackie only used one of the angles, not both. The correct equation is: x+16+x=90

Answer:

Jackie forgot to add variable X

Step-by-step explanation:

Jackie Did

X +16= 90

equation :

Answer:

609m^2

Step-by-step explanation:

Area of the nonshaded part  = (6*11) + (13*7)

Area of the nonshaded part = 66+ 91

Area of the nonshaded part  = 157m^2

Area of the whole figure = (28*14) + (17*22)

Area of the whole figure  = 392+374

Area of the whole figure  = 766m^2

Required area  = 766 - 157

Required area   = 609m^2

Answer:

260

Step-by-step explanation:

There are a few ways to solve this, but an easy to understand one is that 39=15%, therefore 13=5%, as it is taking 1/3 of each number. Then to get to 100% we would need to multiply 13=5% by 20 to get 260=100%

Answer:

260

Step-by-step explanation:

39 = 15%

1% = [tex]\frac{13}{5}[/tex]

[tex]\frac{13}{5}[/tex] x 100 = 260

260 x 0.15 = 39 :)

Answer:

x + y + z = 272 - - - - - - (1)

x = 3y - - - - - - - - - - - - - (2)

z = 32 + y - - - - - - - - - - (3)

Step-by-step explanation:

Let :

Number of pop songs = x

Number of rock songs = y

Number of hophops = z

Sum of the three types of songs = 272

x + y + z = 272 - - - - - - (1)

Pop is 3 times Rock :

x = 3y - - - - - - - - - - - - - (2)

Hiphop is 31 more than rock

z = 32 + y - - - - - - - - - - (3)
