A composite figure is formed by combining a square and a triangle. Its total area is 57.5 ft2. The area of the triangle is 32.5 ft2. What is the length of each side of the square? Complete the explanation. The area of the square is ft2, so each side of the square is ft.
Answer:
Area of square = Composite Area - Area of Triangle
= 32.5 - 7.5 = 25
Area of square = 25 square feet.
Formula for area of square = s²
s² = 25
s = √25
s = 5
Length of each side of square = 5 feet.
Question:
A composite figure is formed by combining a square and a triangle. Its total area is 31.5 ft2. The area of the triangle is 15.5 ft2. What is the length of each side of the square? Complete the explanation.
Answer:
The area of the square is 16 ft², so each side of the square is 4 ft.

The square has an area of x^2-10x+25 what is the side length
Answer:
(x-5)
Step-by-step explanation:
Factors to be (x-5)^2 so each side is (x-5)
find the slope of the line passing through the points (5, 6) and (5,-8)
Answer:
Undefined
Step-by-step explanation:
Slope is equal to the change in y over the change in x.
m = (y₂ - y₁) / (x₂ - x₁)
Let your points (5, 6) be (x₁, y₁) and (5,-8) be (x₂, y₂). Therefore you have
m = (-8 - 6) / (5 - 5) = -14 / 0
Dividing by zero will lead you to have an undefined slope

Ms. Morales showed her geometry students the figure below and told them that DE || BC. She asked them to use this information to prove that DE divides AB and AC proportionally.
Answer: B
Step-by-step explanation:
9. DOG WALKING Evan, a dog walker, charges $3 every block that he walks a dog. He also charges a $5 pick up fee when he comes to get a dog. How many blocks will he need to walk a dog in order to earn $26? Write an equation and solve the equation.
Answer:
Evan will have to walk 7 blocks
Step-by-step explanation:
Evan will have to walk 7 blocks because he gets $5 from picking up the dog, so subtract 5 from 26 to get 21. Next, you want to divide 21 by 3 to get 7 because $3 a block and you need to find how many blocks he needs to do.
Use the portion of the periodic table shown below to answer the questions.
A portion of the first three columns of the periodic table is shown. Column one from top to bottom reads 11 sodium 22.990, 19 potassium 39.098, and 37 rubidium 85.468. Column two reads 12 magnesium 24.305, 20 calcium 40.078, and 38 strontium 87.62. Column three reads 21 scandium 44.956 and 39 yttrium 88.906.
Part 1: Name two elements that have the same properties as magnesium (Mg). (4 points)
Part 2: Determine the number of protons, electrons, and neutrons present in an atom of potassium (K). Explain how you determined your answer using complete sentences. (6 points)
Part 1:
Calcium(Ca) And Strontium (Sr)
Part 2:
Protons: 19
Electrons: 19
(both are the same)
Neutrons:20

In the diagram below, AC intersects ABDE at B. Choose True or False for each statement
Answer:
false, true . false
Step-by-step explanation:
if u want an explanantion you can ask me :)
Answer: a. True b. True c. False
Explanation:
a. 65+25 =90 complementary angles add up to 90°
b. 65 + b + 25 = 180
90 + b = 180
b = 180 - 90
b = 90
Check-
65 + 25 + 90 = 180
90 + 90 = 180
180 = 180 ✅
c.not vertical angles because they aren’t across from eachother

In △ A B C , the measure of angle A is 103 ° and the measure of angle B is 37 ° . What is the measure of angle C ?
Step-by-step explanation:
103° + 37° + < C = 180° { being sum of angles of triangle }
< C = 180° - 140°
< C = 40°

In the circle below, Ab and CD are chords intersecting at E if AE=5, BE,12, and CE=6, what is the length of DE
Answer:
DE = 10
Step-by-step explanation:
Here, we want to find the value of DE
we use the intersecting chord principle
That will be;
CE * ED = AE * BE
we have;
6 * DE = 5 * 12
DE = (5 * 12)/6
DE = 5 * 2
DE = 10

The rectangle below has an areas of x^2+8x+15 square metres and a width of x+3 meters what expression represents the length of the rectangle
Answer: x+5 or ((x^2+8x+15)/(x+3))
Step-by-step explanation: First let's assign our variables.
x^2+8x+15 = Area
X+3 = Width
? = Length
If the equation of a=lw, then we can substitute in our variables.
a=lw
x^2+8x+15= L (x+3)
Now we must isolate L.
Divide both sides of the equation by 'x+3'
x^2+8x+15= L (x+3)
x+3 x+3
x+5= L
