Hi I NEED HELP FAST IGNORE 1 and 3 I ONLY NEED 2
Answer:
The answer to 2 is No, because the sum of two sides must be larger than the third.
Could anyone please help me with this? I don't get this
Answer:
23
Step-by-step explanation:
the angles are equal to each other so we use the equation
6x-7=9x-22 and solve for x
step 1 subtract 6 from each side
-7=3x-22
step 2 add 22 to each side
3x=15
step 3 divide each side by 3
x=5
then to find the angle abd we plug in 5 to 9x-22
9x5=45
45-22=23 so angle abd=23
hope this helps (:

find the exact value of the composite function show work
Answer:
[tex]\frac{2x}{\sqrt{4x^{2} -1} }[/tex]
Step-by-step explanation:
This function can be written as:
[tex]\frac{1}{cos(sin^{-1}(\frac{1}{2x})) }[/tex]
[tex]sin^{-1}(\frac{1}{2x})[/tex] means the angle whose sine is 1/(2x). This implies that the denominator is the cosine of the angle whose sine is 1/(2x)
Think of a right triangle and consider the angle with this sine. Then the opposite side has length 1 and the hypotenuse has length 2x. The Pythagorean theorem then implies that the adjacent side is
[tex]\sqrt{4x^{2} -1}[/tex]
The cosine of the angle is adjacent over hypotenuse, so the cosine is
[tex]\frac{\sqrt{4x^{2} -1}}{2x}[/tex]
The secant is the inverse of the cosine, so the answer is
[tex]\frac{2x}{\sqrt{4x^{2} -1} }[/tex]

Maggie says that if the expression was 12÷3to the second power, you would divide before simplifying 3 to the second power. Is she right? Explain
Answer:
Maggie is incorrect.
Step-by-step explanation:
PEMDAS tells us the order of operations and the steps of solving a mathematical statement. It states that exponents must be performed before multiplication or division.
P - Parentheses
E - Exponents
M - Multiplication
D - Division
A - Addition
S - Subtraction
Therefore, to solve 12÷3² correctly, 3² needs to be simplified to 9 before dividing.

what is the slope and y-intercept for 6x-2y=16
Answer:
x= (8/3,0)
y=(0,-8)
Step-by-step explanation:
Answer:
slope = 3/1
y-intercept is (0, -8)
Step-by-step explanation:
6x - 2y = 16
-2y = -6x + 16
y = -6/-2x + 16/-2
y = 3x - 8

Tell whether (4, 27) is a solution of y=3x+15
Answer:
Yes
Step-by-step explanation:
We have two properties for our question :
(4, 27)
y = 3x + 15
We are being asked whether the point (4, 27) is a solution of y = 3x + 15
So how do we figure this out? Well, what we have to know first that (4, 27) represents a variable, 4 which is the run on the graph, represents x in a solution. And 27 which is the rise on the graph, represents y in the solution. So when asking for a solution with two points, all we must do is substitute x and y for the two coordinates.
y = 3x + 15
y = 27 and x = 4
27 = 3(4) + 15
27 = 12 + 15
27 = 27
Since this equation is true with the respected variables, therefore signifies that (4,27) is a solution of y = 3x + 15

Find the value of x.
Answer:
C
Step-by-step explanation:
We're given the adjecent and we're looking for the hypotenuse so we'll have to use cosine ratio.
11 / cos 38 = 13.959.....
x = 14.0
We can also use the tangent ratio to look for the opposite and then use pythagorean to find the hypotenuse.
11(tan 38) = 8.594......
8.594.....² + 11² = 194.859......
Square root of 194.859..... = 13.959.......
The area of a square is 4x^2+28x+49. What expression represents the length of each side of the square?
Answer:4x^2 +28x +49=(2x +7)^2
Step-by-step explanation:
a2±2ab+b2=(a±b)2
In this case
a=2x and b=7 ...
4x2+28x+49=(2x)2+(2⋅
(2x)⋅
7)+72=(2x+7)2
The expression that represents the length of each side of the square is (2x + 7)(2x + 7)
What is expression?Expressions in math are mathematical statements that have a minimum of two terms containing numbers or variables, or both, connected by an operator in between.
Given that an expression showing the area of a square, 4x²+28+49,
The length of the side of the square will be the factors of the expression,
Therefore, factorizing, 4x²+28+49,
4x²+28+49
= 4x² + 14x + 14x + 49
= 2x(2x + 7) + 7(2x + 7)
= (2x + 7)(2x + 7)
Hence, the expression that represents the length of each side of the square is (2x + 7)(2x + 7)
