b. What is the correct expanded form of
(x + 5)(2x + 3)?
The expanded form of the expression is 2x²+13x+15, and Tyler's mistake is, he should multiply the terms not to add the terms.
What is expression?The definition of an expression in math is a statement composed of terms and operations. The terms may be constant (numbers), or variables with coefficients. The operations may be addition, subtraction, multiplication, or division.
Given is an expression, (x + 5)(2x + 3), Tyler tried to solve it with the help of a diagram, but had some mistake,
We need to identify his mistake and write the expression in the expanded form,
So,
Making the diagram,
2x 3
x (x·2x = 2x²) (3·x = 3x)
5 (5·2x = 10x) (5·3 = 15)
Now, adding the terms,
We have,
2x² + 10x + 3x + 15
= 2x²+13x+15
Hence, the expanded form of the expression is 2x²+13x+15, and Tyler's mistake is, he should multiply the terms not to add the terms.

The area of a rectangle is 108 m2 and its diagonal is 15 m. Find
the perimeter of the rectangle.
Please help
Answer:
42m
Step-by-step explanation:
Let's call the rectangle ABCD. Since this is a rectangle, the triangles inside this rectangle (ΔACD and ΔABD) are both right triangles because of the definition of a rectangle. In addition, AB = CD and AC = BD because of the definition of a rectangle. Since AD = 15 (The Diagonal), you can say that because of Pythagorean Triples that AC = 9 and CD = 12 (3 : 4 : 5 = 9 : 12 : 15). Since we stated that AB = CD and AC = BD, we can say that the perimeter of ABCD is equal to 9 + 9 + 12 + 12. 9 + 9 + 12 + 12 is equal to 42.
Therefore: Perimeter of ABCD = 42

Answer:
a. t = 98
b. b = 32
Step-by-step explanation:
4/7t - 20 = 36r; r = 1
4/7t - 20 = 36(1)
4/7t = 36 + 20
4/7t = 56
7/4 x 4/7t = 56 x 7/4
t = 98
2/5k = 1/2b - 12; k = 10
2/5(10) = 1/2b - 12
4 = 1/2b - 12
4 + 12 = 1/2b
16 = 1/2b
16 x 2/1 = 1/2b x 2/1
b = 32
Check:
a.) 4/7t - 20 = 36r; r = 1; t = 98
4/7(98) - 20 = 36(1)
(56) - 20 = 36
36 = 36 ✅
b.) 2/5k = 1/2b - 12; k = 10; b = 32
2/5(10) = 1/2(32) - 12
2/5(10) = (16) - 12
4 = 16 - 12
4 = 4 ✅

Need help plz I’m stressed
Answer:
Step-by-step explanation:
this a educatated gues and i wanna say B or C bc the line is positive so im leaning towards c more but you can choose ?
As per the coordinates of the labeled point, the point-slope equation of the line is y + 5 = 2(x+ 2).
What is a slope?In mathematics, a line's slope, also known as its gradient, is a numerical representation of the line's steepness and direction.
If a line passes through two points (x₁ ,y₁) and (x₂, y₂) ,
then the equation of line is
y - y₁ = (y₂- y₁) / (x₂ - x₁) x (x - x₁)
To find the slope;
m = (y₂- y₁) / (x₂ - x₁)
To find the equation of a line passing through two given points, we can use the point-slope form of the equation of a line:
First, let's find the slope of the line:
m = (y2 - y1) / (x2 - x1)
m = (5 - (-5)) / (3 - (-2))
m = 10 / 5
m = 2
Next, we can choose one of the given points to use in the point-slope form. Let's use (-2, -5):
y - (-5) = 2(x - (-2))
y + 5 = 2(x + 2)
Therefore, the equation is y + 5 = 2(x + 2).

A trip to another city is 180 miles. In miles per hour to the nearest tenth, how fast does one have to drive to average 60 mph on a three-hour trip during which one stops for 10 minutes? (Enter the answer in the form ab.c.)
Answer:
63.5
Step-by-step explanation:
If one didn't take a 10 minute break he could drive 60 mph totalling 180 minutes but since he did and 180 - 10 = 170. He/she has to drive 180 miles in 170 min. so we take so we divde 180/170 and multiply by 60. If you round it to the nearest tenth you get 63.5

A. Translation 3 units up
B.translation 3 units down
C.translation 3 units to the right
D.translation 3 units to the left
Answer:
3 units left (negative so it has to be left or down)
Step-by-step explanation:
It could also be 3 units down though.
Also if I'm right are you giving brainliest?
The graph of the Beth will shift 3 units right after performing the transformation x → (x-3) to the function option (C) is correct.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
We have:
For Beth:
[tex]\rm y= x^2 + 1[/tex]
For Jacob:
[tex]\rm y= (x - 3)^2 + 1[/tex]
Plug x → (x-3) in the Beth equation's we will get Jacob graph of equation.
The graph of the Beth will shift 3 units right after performing the transformation to the function.
Thus, the graph of the Beth will shift 3 units right after performing the transformation x → (x-3) to the function option (C) is correct.
