Answer:
what are you trying to find?
after multiplying,we have a(b plus c)
Answer:
The Distributive Property is easy to remember, if you recall that "multiplication distributes over addition". Formally, they write this property as "a(b + c) = ab + ac". In numbers, this means, for example, that 2(3 + 4) = 2×3 + 2×4.

Johnny is 5 years younger than 3 times the age of Johnson, please write an expression for Johnny's age. If Johnson is 4 years old, how old is Johnny?
Answer:
Johnny is 7
Step-by-step explanation:
multiply 4 by 3 as johnny is 5 years younger then 3 times the age of Johnson and Johnson is 4 so we get 12 then we subtract 5 and get 7
A zip line from the tallest tree in the forest to the campsite is 145 feet. The angle of elevation from the ground to the top of the tree is 58°. How tall is the tree? Round your answer to the nearest foot.
Answer:
123 ft
Step-by-step explanation:
create a right angle triangle from the given info.
your perpedicular will be tree height and hypotneus will be 145 feet
sin 45=Tree height/145
122.96=tree height
123 ft
The height of the tree will be equal to 123 feet.
What is trigonometry?The branch of mathematics that sets up a relationship between the sides and the angles of the right-angle triangle is termed trigonometry.
The trigonometric functions, also known as a circular, angle, or goniometric functions in mathematics, are real functions that link the angle of a right-angled triangle to the ratios of its two side lengths.
Given that a zip line from the tallest tree in the forest to the campsite is 145 feet. The angle of elevation from the ground to the top of the tree is 58°.
Create a right-angle triangle from the given info. your perpendicular will be tree height and your hypotenuse will be 145 feet

a dilation of figure 1 with scale factor 3/2 then a translation
a dilation of figure 1 with scale factor 3/2 then a reflection
Answer:
Option (4)
Step-by-step explanation:
Length of segment between two points [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by,
d = [tex]\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
From the figure attached,
Distance between A(0, -3) and B(3, 0) = [tex]\sqrt{(3-0)^2+(0+3)^2}[/tex]
AB = [tex]3\sqrt{2}[/tex]
Distance between A'(-3.5, -4.5) and B'(-8, 0)
Length of A'B' = [tex]\sqrt{(-3.5+8)^2+(-4.5-0)^2}[/tex]
A'B' = [tex]4.5\sqrt{2}[/tex]
Scale factor for dilation = [tex]\frac{4.5\sqrt{2}}{3\sqrt{2}}=1.5[/tex]
Therefore series of transformations will be,
A dilation of figure 1 with scale factor of [tex]\frac{3}{2}[/tex] and then a reflection.

The perimeter of the rectangle below is
118 units. Find the length of side AB
.
This a question about perimeter and equation, let's see how to solve that:
The perimeter of a rectangle is the sum of its 4 sides. In this case, we know that the perimeter is 118. We can do an equation with these datas:
[tex]\boxed{AB + BC + CD + DA = 118}[/tex]
We also know other informations: the side AB is equal to [tex]4y+3[/tex] and de side BC is equal to 3y. In a recltangle, parallels sides have the same value. So, the side CD is equal to [tex]4y+3[/tex] and the side DA is equal to 3y.
Now, we have these datas:
[tex]AB + BC + CD + DA = 118\\\\AB = CD = 4y + 3\\BC = DA = 3y[/tex]
Let's do and solve an equation:
[tex]AB + BC + CD + DA = 118\\\\4y+3 + 3y + 4y+3 + 3y = 118\\14y + 6 = 118\\14y = 118 - 6\\14y = 112\\y = \frac{112}{14} \\y = 8[/tex]
So, the value of y is 8. Let's replace the value of y in the side AB:
[tex]4y + 3\\4\times 8 + 3 = 35[/tex]
Therefore, the length of side AB is 35.

A circle has an area of approximately 78.5 square units. If the center of the circle is at Left-parenthesis 2 comma 4 right-parenthesis. Which of the following points is on the circle? A. Left-parenthesis negative 6 comma 4 right-parenthesis B. Left-parenthesis 2 comma negative 1 right-parenthesis C. Left-parenthesis negative 4 comma negative 4 right-parenthesis D. Left-parenthesis 2 comma negative 9 right-parenthesis
Answer:
The answer is (2, -1)
Step-by-step explanation:
The area of the circle is:
A = r²π
We know
A = 78.5
π = 3.14
78.5 = r² * 3.14
r² = 78.5 : 3.15
r² = 25
r = √25 = 5
The standard form equation of a circle is:
(x - h)² + (y - k)² = r²
We have:
(2, 4)
⇒ h = 2
k = 4
r = 5
(x - h)² + (y - k)² = r²
(x - 2)² + (y - 4)² = 5²
(x - 2)² + (y - 4)² = 25
Now, let's substitute all choices:
(-6, 4):
(-6 - 2)² + (2 - 4)² = 25
(-8)² + (-2)² = 25
64 + 4 = 25
68 = 25
Wrong
(2, -1)
(2 - 2)² + (-1 -4)² = 25
0² + (-5)² = 25
0 + 25 = 25
25 = 25
Right

Tom performs a dilation of ⅓ on a triangle. He then classifies the image and pre-image as being congruent. Is Tom correct? Why or why not? Explain you answer down below.
Answer: Tom is incorrect.
Step-by-step explanation: Congruent is defined as having exactly the same angle measurements and exactly the same side lengths.
In the 1/3 dilation, the angles will remain the same, but all the sides will be shorter, 1/3 the lengths of the original image. The image and pre-image are not congruent. They are similar.
Find the value of x for which the lines a and b are parallel.

Answer:
x = 19
Step-by-step explanation:
148 and 7x+15 are alternate interior angles and alternate interior angles are equal when the lines are parallel
148 = 7x+15
Subtract 15 from each side
148-15 = 7x+15-15
133 =7x
Divide each side by 7
133/7 =7x/7
