10x2 + 31x + 24
(2x + 3)(5x + 8)

Answer:

Step-by-step explanation:

So the sum of 128 and x+10 is on a straight line which is 180º right?, so:

x + 10 + 128 = 180

x = 180 - 128 - 10

x = 42º

Answer:

42

Step-by-step explanation:

x +10 +128 = 180   {Linear pair}

x  + 138 = 180

x = 180 - 138

x = 42

Step-by-step explanation: Circumference of a circle is 2πr

76=2×3.14×r

r= 76÷(6×3.14)

r=12.10

Area of a circle= πr^2

Area= 3.14×(12.10)^2

Area= 456.73cm^2

Answer:

If you‘re looking for the Circumference of a circle (since i didn’t really understand your question) C = 3 x 3.14 x radius (C is circumference aka perimeter btw)

Step-by-step explanation:

the perimeter is easy.

it is an isoceles triangle, that means both sides are equally long (10 units).

the length of the baseline we can read directly off the coordinates of P and Q.

both are on the same horizontal grid line y = 1. so, the difference in x is their distance : 8 - -8 = 8+8 = 16

so, the perimeter is 10 + 10 + 16 = 36 units.

now, for k :

k is the height of the triangle + 1 (as the baseline is at y=1 and not at 0).

we can get the height by using Pythagoras :

c² = a² + b²

c is the Hypotenuse (the baseline) of the dude opposite of the 90° angle.

the triangle we use for this is

PR, half of PQ and the height of the main triangle, with PR being the Hypotenuse.

so,

10² = (16/2)² + height² = 8² + height²

height² = 10² - 8² = 100 - 64 = 36

height = 6

therefore, k = 6 + 1 = 7

The triangle that does not have the y angle, equate all of its angles to 180 degrees and solve for x. Once you solve for x, substitute that value to the angles in the other triangle, and then add them all up and equate it to 180 degrees to solve for y.

Based on the centroid theorem, the value of x is: 2.5.

The centroid theorem states that, the centroid of a triangle equals two-third of the distance from each midpoint of a triangle to each vertex.

Given:

BD = 4x + 5

BF = 9x

Thus:

BD = 2/3(BF)

4x + 5 = 2/3(9x)

4x + 5 = 6x

4x - 6x = -5

-2x = -5

x = 5/2

x = 2.5

Therefore, based on the centroid theorem, the value of x is: 2.5.

M=Multiplication

D=Division

Multiplication is done before division.

So, multiply 1.21*2 for the first problem, and 1.20*2 for the other 2 problems.

1.

24/(1.21)2 becomes 24/2.42

24/2.42= 9.9173553719 (or 9.92 rounded, or 9.9)

2.

29/(1.20)2 becomes 29/2.4

29/2.4= 12.0833333333 (or 12.08 rounded, or 12.1)

Answer:

A. $202.80 EDGE

Step-by-step explanation:

The predicted price of a set that has 2,520 pieces is $202.8.

The correct option is (A).

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given:

y = 0.08x + 1.20

where x represents the number of pieces in a set and y is the predicted price.

So, for x= 2520 pieces the predicted price is

y= 0.08(2520)+ 1.20

y= 201.6 + 1.5

y= $202.80

Hence, the predicted price is $202.8.

Answer:

y=x+8

Step-by-step explanation:

m=y2-y1/x2-x1

First you choose one of your coordinate points to be 1 and one to be 2.

Then you substitute your x and y values into the equation above.

That way, you find the slope of the line.

For example i chose (-4,4) to be point 1 and (2,10) to be point 2.

m=10-4/2-(-4)

m=6/6

m=1

Next, you write the equation of a line.

y=mx+b

and you substitute the x and y values of one coordinate point into the equation. You also put m(slope) in, the one you just solved for.

I chose to substitute (2, 10)

10= 1(2)+b

Next, you solve for b

10=2+b

10-2=b

b=8

Now that you have b and your slope, you substitute those into the second equation

y=1x+8 or

y=x+8
