Answer:
2(3x2 + 6x - 10) + 2(3x + 5)
Step-by-step explanation:
Answer:
Lol. Give brainliest to the other guy.
Step-by-step explanation:
To find the width, multiply the length that you have been given by 2, and subtract the result from the perimeter. You now have the total length for the remaining 2 sides. This number divided by 2 is the width.
Which equation of an exponential function has a graph that passes through the points
(1,5) and (2,15)?
Answer:
[tex]y = \frac{5}{3} (3^{x} )[/tex]
Step-by-step explanation:
In general, [tex]y = k(b^{x})[/tex]
Substitute x = 2, y = 15
(1) [tex]15 = kb^{2}[/tex]
Substitute x = 1, y = 5
(2) [tex]5 = kb^{1} = kb[/tex]
Divide equation (1) by equation (2)
[tex]\frac{15 = kb^{2} }{5= kb }[/tex]
3 = b
Now substitute b = 3 in equation (2) to find k
5 = k(3)
[tex]k = \frac{5}{3}[/tex]
Since we know the values for k and b, we now have the exponential function that passes thru (1, 5) and (2, 15)
[tex]y = \frac{5}{3} (3^{x} )[/tex]

ive done this before and the answer to the equation is c and also truss me on this if you want. I wouldnt
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.

Write the linear equation in slope intercept form of a line that is not parallel or perpendicular to y = x - 4
Answer:
y = xa - (4 + b)
where a or b do NOT = 1
Step-by-step explanation:
changing a changes the angle of the line, where as changing b changes how high up or down the y-axis the line crosses at
the current problem draws a line that is 45 degrees and crosses the y-axis at -4, we can change that in any way, if we make a = 3, then the slope will be 3 times greater then if it was 1, if it was 1/3 then it would be 1/3 of the slope, making it seem flatter and less steep
i hope this helps you create your own formulas now and in the future, this is a reference sheet i made for my own schooling, though i used a different example problem

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°

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...

Given :
Given that:
Texas= 2.5x10^5
Carolina = 1.2x10^3
Comparing the size of Texas and Carolina
Texas / Carolina
(2.5 * 10^5) ÷ 1.2 * 10^3
(2.5/1.2) * 10^5-3
2.08333 * 10^2
Hence, Texas is 2.08333 * 10^2 times the size of Carolina.
