Plz, answer this question plz!
If the function h is defined by h(x)=[tex]x^{2}[/tex]-3x+5,then h(2x+1)=
Given:
The function is:
[tex]h(x)=x^2-3x+5[/tex]
To find:
The value of [tex]h(2x+1)[/tex].
Solution:
We have,
[tex]h(x)=x^2-3x+5[/tex]
Putting [tex]x=2x+1[/tex], we get
[tex]h(2x+1)=(2x+1)^2-3(2x+1)+5[/tex]
[tex]h(2x+1)=(2x)^2+2(2x)(1)+(1)^2-3(2x)-3(1)+5[/tex]
[tex]h(2x+1)=4x^2+4x+1-6x-3+5[/tex]
On combining like terms, we get
[tex]h(2x+1)=4x^2+(4x-6x)+(1-3+5)[/tex]
[tex]h(2x+1)=4x^2-2x+3[/tex]
Therefore, the required function is [tex]h(2x+1)=4x^2-2x+3[/tex].

Step 3: x^2+ 16x +
Answer:
Step 3: x² + 6x + 64 = -8 + 64
Step-by-step explanation:
At step 3 add 64 on both sides to complete the square.
so x² + 6x = -8
becomes x² + 6x + 64 = -8 + 64 when 64 is added both sides giving us step 3.
continuing from there, we get
x² + 6x + 64 = 56
we then use a² + 2ab + b² = (a + b)² on the left side to get
(x + 8)² = 56 (solve the equation for x)
by taking the root on both sides
√(x + 8)² = √56
x + 8 = +- 2√14 (separate the equations
x + 8 = 2√14
x + 8 = -2√14
Solving for x
x = 2√14 - 8 or x = -2√14 - 8

Since 4 is less than 134, the correct expression will be:
4 < 134
Since 3 is less than 5, the correct expression will be:
3 < 5
Since 351 is greater than 215, the correct expression will be:
351 > 215
Step-by-step explanation:
The greater a decimal is, the closer it is to one whole. The smaller a decimal is the farther it is from one whole. The first thing you need to look at is the digit number in each decimal. These each have two digits in them, so you can compare them right away

Step-by-step explanation:
The area of the given triangle in the image is 74.8m².
What is a triangle?A triangle is simply a polygon with three vertices with three edges.
A scalene triangle is the triangle with no equal sides and angles.
It area can be calculated using the expression;
A = 1/2 × absinθ
Given the data in question;
Length of side a = 15mLength of side b = 11mLength of side c = 22mAngle C = 115°
To determine the area of the triangle, we substitute our given values into the expression above.
A = 1/2 × absinθ
A = 1/2 × 15m × 11m × sin( 115° )
A = 0.5 × 15m × 11m × 0.9063
A = 74.76975m²
A = 74.8m²
Therefore, the area of the given triangle in the image is 74.8m²
