Answer:
15v^5 +4v^3 -24v^2
Step-by-step explanation:
Distributing the minus sign, we have ...
3v^5 +8v^3 -10v^2 +12v^5 -4v^3 -14v^2
= (3 +12)v^5 +(8 -4)v^3 +(-10 -14)v^2
= 15v^5 +4v^3 -24v^2

Step-by-step explanation: Triangle angle sum theorem states the interior angles of a triangle sum to 180 degrees. We know one angle is 40 degrees and the two remaining angles are equal in measure.
Since angle J and angle L are equal in measure we can substitute 2x for angles J and L into the equation.
40 + 2x = 180. Subtract 40 from both sides.
2x = 140. Divide both sides by 2.
X = 70

Find the surface area of the triangular pyramid.
a triangular pyramid - the base has side length 2.5 inches and height 2.2 inches and each face has height 5 inches
Answers
Answer:
31.25 in²
Step-by-step explanation:
Surface area of triangular pyramid
Perimeter, P = 4s = 4 * 2.5 = 10 inches
Lateral surface area = 0.5 * P * height = 0.5 * 10 * 5 = 25 inch²
The base area = s² = 2.5² = 6.25 inch²
Hence, surface are ao triangular pyramid ;
Lateral surface area + base area
= 25 inches + 6.25 inch²
= 31.25 in²

The relative frequency that the traffic lights will show GREEN at road works is 0.7. Estimate how many times they would be RED over the next 40 journeys?
Answers
Answer:
28 reds are expected over the next 40 journeys
Step-by-step explanation:
Here, we want to get the number of reds in the next 40 journeys
From the question, we have that the relative frequency is 0.7
Thus, for the number of reds, we have to multiply the relative frequency by the number of journeys
We have this as;
40 * 0.7 = 28

Explain why this common mistake is wrong. Many people might say that (2, 4) is an intercept of the equation 5x + 2y = 18.
Answers
Answer:
Step-by-step explanation:
(2,4) is point lying on the line represented by 5x + 2y = 18.
They are not intercepts.
x-intercept is point where the line crosses the x-axis and so, y-co ordinate at x-intercept is 0.
y-intercept is point where the line crosses they-axis and so,x-co ordinate at y-intercept is 0.
5x + 2y = 18
To find x-intercept, put y = 0 in the equation
5x = 18
x = 18/5
x = 3.6
To find y-intercept, put x = 0 in the equation
2y = 18
y = 18/2
y = 9
x-intercept : (3.6 , 0)
y-intercept :(0, 9)
