Answer:
5x^2-4+4(x^2)-6x
Step-by-step explanation:
first you need to remove the unnecessary parentheses it should look like this: 5x^2-7-(4(x^2)+6x-3)
then you should calculate the sum it should look like this: 5x^2-4+4(x^2)-6x and that is your answer
In ΔNOP, p = 72 inches, o = 84 inches and ∠O=19°. Find all possible values of ∠P, to the nearest degree
Answer:
16
Step-by-step explanation:
The value of the angle m∠P is given by the law of sines and m∠P = 16°
What is the law of sines?The relationship between a triangle's sides and angles is provided by the Law of Sines. Trigonometry's law of sines can be expressed as a/sinA = b/sinB = c/sinC, where a, b, and c are the lengths of the triangle's sides, and A, B, and C are the triangle's respective opposite angles.
Law of Sines :
a / sin A = b / sin B = c / sin C
Given data ,
Let the triangle be represented as ΔNOP
Now , the measure of side p = 72 inches
The measure of side o = 84 inches
And , the measure of angle ∠O = 19°
From the law of sines , we get
a / sin A = b / sin B
On simplifying , we get
sin p / 72 = sin o / 84
Multiply by 72 on both sides , we get
sin p = ( 72 / 84 ) sin ( 19 )°
On further simplification , we get
sin p = ( 0.857 ) x 0.325568
sin p = 0.279058
Taking inverse on both sides , we get
p = sin ⁻¹ ( 0.279058 )
p = 16.204°
Therefore , the value of p is 16°
Hence , the measure of angle ∠P = 16°

In quadrilateral RSTU in the coordinate plane, RS | TU and RS = 6. Which additional statement allows you to conclude that RSTU is a
parallelogram?
Answer:
A. ST = RU
Step-by-step explanation:
Quadrilaterals are four sided figures. Examples are: square, rectangle, trapezium, parallelogram etc. A parallelogram is a quadrilateral that has equal opposite and parallel sides.
This implies that in the given question since RS || TU, then;
RS = TU = 6
So that for RSTU to be a parallelogram,
ST = RU
Thus, the appropriate option to the question is A.

The measure of an angle is nine times the measure of its complementary angle. What is the measure of each angle?
Answer:
the angle is 81 and it's complementary angle is 9
let X be the angle
let 90-x be it complementary angle
so X=9(90-x)
X=810-9x
810=10x
X=810/10
X=81
and complementary angle 90-x which is 90-81 is equal to 9...

The inequality that describes the possible value of x is 2< x < 22.
What is inequality?In mathematics, "inequality" refers to a relationship between two expressions or values that is not equal to each other. Therefore, inequality emerges from a lack of balance.
Given that ∠A = 50°
AB ≈ DE ≈ EF
BC = 12
CD = 10
And the ∠E = (5x - 10)°
From the Graph, we can see that Angle A is the alternate angle to angle G
Alternate angles are the angles that occur on opposite sides of the transversal line. We can easily spot two interior alternate angles by drawing Z. The value of alternate angles is equal.
thus, ∠A = ∠E
50° = 5x -10
5x = 60
x = 12
Therefore, from the given options the value of x lies in the inequality 2 < x < 22.

calculate the range of the data. *
(1 Point)
104, 117, 104, 136, 189, 109, 113, 104
Answer:
The range here is 85
Step-by-step explanation:
Here, we want to calculate the range of the data
Mathematically, the range is defined as the difference between the lowest value and the highest value in the dataset
From the given data points, the highest value is 189, while the lowest value is 104
So the range is the difference between the two which is;
189-104 = 85
Which statement is true?
Answer:
Step-by-step explanation:
x-intercept -> when y = 0
f(x) x-intercept -> (1 , 0)
g(x) x-intercept -> (-1 , 0)
y-intercept -> when x = 0
f(x) y-intercept -> (0 , -1)
g(x) y-intercept -> (0 , 1)
The x-intercept of f(x) is greater than the x-intercept of g(x)
The y-intercept of g(x) is greater than the y-intercept of f(x)
So from the options, the answer is D. The x-intercept of f(x) is greater than the x-intercept of g(x)
