Answer:
(6x + 5)(x + 2)
Step-by-step explanation:
x coefficients must multiply to 6
so 6 * 1 or 2*3
10 must be 5*2 or 1* 10
(6x + 5)(x + 2) = (6x² + 12x + 5x + 10) = 6x² + 17x + 10

Express f(1) = log(100)
= log( 200 ) in the general form of a logarithmic function
g(x) = k + a log b(x – h).
a= -3
b= 1
k = 2
h= 0
refer to the attachment
The logarithmic equation f(x) = log(100) in the form g(x) = k + a log b(r – h) is f(x) = 0 + 2log(10 - 0)
What is logarithmic equation?In mathematics, the logarithm is the inverse function to exponentiation. That means the logarithm of a number x to the base b is the exponent to which b must be raised, to produce x. For example, since 1000 = 10³, the logarithm base 10 of 1000 is 3, or log₁₀ = 3.
Here, we have,
to rewrite the logarithmic equation:
The equation is given as:
f(x) = log(100)
Express 100 as 10^2
f(x) = log(10^2)
Apply the law of logarithm
f(x) = 2log(10)
Subtract 0 from 10
f(x) = 2log(10 - 0)
Add 0 to the equation
f(x) = 0 + 2log(10 - 0)
Hence, the logarithmic equation f(x) = log(100) in the form g(x) = k + a log b(r – h) is f(x) = 0 + 2log(10 - 0)

Part (a)
The angles would stay the same. This is because similar figures keep the same shape, but the size will shrink or grow.
A real world application is to simply move your head closer to the page and the figure will appear to get larger. The angles themselves stay the same but the side lengths will get larger.
====================================================
Part (b)
While the angles stay the same under a dilation operation, the side lengths do not. As the instructions state: "The side lengths are 3 times longer" (paraphrased).
So we multiply each side length in the diagram by 3
DE = 3*JK = 3*4.5 = 13.5EF = 3*KL = 3*3 = 9FG = 3*LM = 3*2 = 6GD = 3*MJ = 3*2.5 = 7.5Refer to the diagram below. I've used the resize feature to enlarge the image to make figure DEFG

Using Substitution 4x-3y=-10 and x=1/4y-1
Answer:
Then the solution is (-1/4, 3)
Step-by-step explanation:
Start by eliminating the fractional coefficient 1/4: multiply all 3 terms in the second equation by 4. This results in equation (b), below:
4x - 3y = -10 (a)
4x = y -4 (b)
Substitute y - 4 for 4x in equation (a):
y - 4 - 3y = -10
Combining like terms, we get -2y = -10 + 4, or -2y = -6, or y = 3.
Since x = (1/4)y - 1, if y = 3, then x = (1/4)(3) - 1, or x = 3/4 - 1, or x = -1/4
Then the solution is (-1/4, 3)
Can someone please help me with this, it’s urgent!!

Answer:x

permiter=6
area=24
Step-by-step explanation:
Answer:
x = 8, area = 364 km^2, perimeter = 80 km
Step-by-step explanation:
to start, we have to recognize that opposite sides of a rectangle are congruent.
therefore ➪
2x + 10 = 4x - 6
2x + 16 = 4x
16 = 2x
x = 8
now just plug that in and you'll find ➪
length = 26km
width = 14km
area = l * w
area = 26 * 14
area = 364 km^2
perimeter = 2(l + w)
perimeter = 2(14+26)
perimeter = 80 km

Answer:
50°
Step-by-step explanation:
The sum of the internal angles of a triangle is always 180°. The PQR triangle have 70° + 60° = 130°, so it need to have more 50° to complete 180°, and the angle x have the same size that this "missing angle" from the PQR triangle because the angle x is formed by the same segments, so it have 50°
Emil is cutting a 72-inch-long board and a 54 in long board into shelving. He wants to make as many shelves as he can while using up all the wood. What is the longest possible length of the shelves?
Answer: The longest possible length of the shelves = 18 inches
Step-by-step explanation:
Given: Lengths of two boards are 72-inches and 54 inches.
To make as many shelves as he can while using up all the wood we will find the longest possible length of the shelves = HCF ( 72, 54)
72 = 2 x 2 x 2 x 3 x 3
54 = 2 x 3 x 3 x 3
HCF(72,54) = 2 x 3 x 3 = 18
Hence, the longest possible length of the shelves = 18 inches

Jerry's Fizzy Cola: 4.1 through 4.3, inclusive
Answer:
D
Step-by-step explanation:
Frizzy cola is 4.1 through 4.3 inclusive
This means that the pH Range of frizzy cola is between 4.1 to 4.3(including 4.3)
If the pH value is represented as h :
The the lower bound will be 4. 1
Upper bound will be 4.3
This means :
4.1 less than or equal to h and h is less than or equal to 4.3
4.1 ≤ h ≤ 4.3
Since, 7 is neutral, values below 7 are acidic while above 7 are alkaline ;
The range is below 7, hence, frizzy cola is acidic.
4.1 ≤ h ≤ 4.3 ; acidic

Identify whether the figure has plane symmetry, symmetry about an axis, or neither. HELP NEEDED NOW!!!
Answer:
The plane figure has a symmetry about an axis
Answer:
plane symmetry and symmetry about an axis
Step-by-step explanation:
A three-dimensional figure has plane symmetry if a plane can divide the figure into two congruent reflected halves.So, the given figure has seven plane symmetries.
A three-dimensional figure has symmetry about an axis if there is a line about which the figure can be rotated by an angle greater than 0∘ and less than 360∘ so that the image coincides with the preimage.So, the given figure has symmetry about seven axes.
Therefore, the figure has plane symmetry and symmetry about an axis.
