What Is the Area of the Triangle?
Step-by-step explanation:
To find the area of a right triangle, you multiply the two legs of the triangle and then divide that result by 2. The reason this works is because a right triangle's area is exactly half the area of a rectangle using the same legs.

HELP!!!!! Consider the polynomial 9x2 – 16. What is the value of ac? What is the value of b? What two numbers multiply to get ac and add to get b? The factored form of 9x2 – 16 is .
Answer:
Below in bold.
Step-by-step explanation:
9x^2 - 16
Comparing this with the standard form
ax^2 + bx + c
ac = 9*-16 = -144
b = 0
-12 and 12 multiply to get ac and add to get b.
Factored form is
(3x - 4)(3x + 4).
The value of ac is,
⇒ - 144
The value of b is,
⇒ b = 0
And, The factored form is,
⇒ (3x - 4) (3x + 4)
What is Quadratic equation?An algebraic equation with the second degree of the variable is called an Quadratic equation.
Given that;
The quadratic equation is,
⇒ 9x² - 16
Now, We know that;
General form of quadratic equation is,
⇒ ax² + bx + c
Here, The quadratic equation is,
⇒ 9x² - 16
Hence, By comparing,
⇒ a = 9
⇒ b = 0
⇒ c = - 16
Thus, The value of ac is,
⇒ ac = 9 × - 16
= - 144
And, The factored form is,
⇒ 9x² - 16
⇒ (3x)² - 4²
⇒ (3x - 4) (3x + 4)
Thus, The value of ac is,
⇒ - 144
The value of b is,
⇒ b = 0
And, The factored form is,
⇒ (3x - 4) (3x + 4)

surface area of a triangular prism
Answer:
54ft squared
Step-by-step explanation:
All faces:
Front: 2*3/2=4.5f squared * 2 (other side)= 9ft squared
Sides: 10*3/2= 15ft squared * 2 (other side)= 30ft squared
Bottom: 3*10/2= 30/2= 15ft squared
=54 ft squared
Surface area of the triangular prism is 96 feet.
What is Surface Area?The area of a three dimensional object on it's outer surface is called the surface area of the object.
A triangular prism has 2 triangular bases and 3 rectangular lateral faces.
Area of a triangle = [tex]\frac{1}{2}[/tex] × base × height
There are 2 triangles at the top and bottom.
Here base = 3 feet and height = 2 feet
Total surface area on the top and bottom = 2 × [tex]\frac{1}{2}[/tex] × base × height
= base × height
= 3 × 2
= 6 feet
There are 3 rectangular faces.
Area of the rectangle = Length × width
Here, length = 10 feet and width = 3 feet
Area of the rectangular face = 10 × 3 = 30 feet
Since there are 3 rectangular faces,
Total lateral surface area = 3 × 30 = 90 feet
Total surface area of the triangular prism = 90 + 6 = 96 feet
Hence the total surface area of the given triangular prism is 96 feet.

5. The distance from the shovel to the treasure chest is
60 yards and the distance from the treasure chest to the
boat is 50 yards. How far is the boat from the shovel?
Answer: 110 yards
Step-by-step explanation:
From the question, the distance from the shovel to the treasure chest is
60 yards while the distance from the treasure chest to the boat is 50 yards. We are to calculate the distance from the boat from the shovel.
The distance from the boat from the shovel will be the addition of the distance from the shovel to the treasure chest which is 60 yards with the distance from the treasure chest to the boat is 50 yards.
= 60 yards + 50 yards
= 110 yards
Solve the volume formula V= /wh for h.
Answer:
V = lwh

Answer:
2784 cm^2
Step-by-step explanation:
I have indicated in the pic there are 4 types of rectangles:
green : 20 x 4 = 80
red : 18 x 4 = 72
yellow : 20 x 18 = 360
blue : 18 x 16 = 288
green has 6 identical surface area so 6 x 80 = 480
red has 4 so 4 x 72 = 288
yellow has 4 so 4 x 360 = 1440
blue has 2 so 2 x 288 = 576
total : 480 + 288 + 1440 + 576 = 2784

A rope is cut so that one piece is three times the length
of the other. Each rope is then used to enclose an area
in the shape of an equilateral triangle. If the area
enclosed by the shorter rope is 1,000 m2, what is the
area enclosed by the longer rope?
Answer:
9,000 m2
Step-by-step explanation:
If the longer rope has three times the length of the shorter rope, the perimeter and the sides of the triangle formed by the longer rope are three times the perimeter and sides of the triangle formed by the smaller rope.
The area of an equilateral triangle is:
[tex]Area = \frac{side^{2} * \sqrt{3}}{4}[/tex]
So, if the side is three times bigger, the area will be 9 times bigger (3^2).
The area of the small triangle is 1000 m2, so the area of the bigger triangle is 9 * 1,000 = 9,000 m2
A line goes through the origin and the point (6, 14). The point (2, y) is also on the line. Calculate y and justify that your value is correct
Answer:
Step-by-step explanation:
The key here is knowing that the equation of the line that passes through these points is same
Thus having (6,14) and (0,0), the slope is as follows;
m = y2-y1/x2-x1 = 0-14/0-6 = -14/-6 = 7/3
Now we can use this slope here to get the value of y in the question
All we need to do is tie write the equation of the line for between the points (6,14) and (2,y)
That would be;
7/3 = y-14/1-6
7/3 = y-14/-5
cross multiply;
-35 = 3(y-14)
-35 = -3y + 42
-3y = -35-42
-3y= -77
y = -77/3
y = 77/3
