Answer:
14.125
Step-by-step explanation:
You combine the two equations and get
8x - 23
and since they're in a 90 degree angle you do
8x - 23 = 90
add 23 to both sides
8x =113
divide 113 by 8 and you get 14.125 and if you plug it in for both x's you get 24.625 + 65.375 you get an even 90
the perimeter is:
4(4x - 6)
Applying distributive property:
4(4x) - 4(6)
16x - 24
Then, the perimeter can also be represented by 16x - 24 because 4(4x - 6) can be simplified to 16x - 24
You have sqrt(8), sqrt(18), and sqrt(2).
You need to simplify the radicals.
sqrt(2) is already simplified.
For both sqrt(8) and sqrt(18), you need to factor out the greatest perfect square.
8 = 4 * 2
You can take the square root of 4 and put it outside the root.
18 = 9 * 2
You can take the square root of 9 and put it outside the root.
Answer:
y^3 - 9y^2 + 26y - 29
Step-by-step explanation:
y - 4[y - 3(y - 2)] - 5
I'm going to separate it into parts
(y - 3)(y - 2)
y^2 - 5y + 6
(y - 4)(y^2 - 5y + 6)
y^3 - 5y^2 + 6y - 4y^2 + 20y - 24
y^3 - 9y^2 + 26y - 24
y^3 - 9y^2 + 26y - 24 - 5
y^3 - 9y^2 + 26y - 29
The area of the figure painted blue, which is 12.2% of the total area is: 4.27 cm².
<h3>What is the Area of a Triangle and Square?</h3>
- Area of triangle = 1/2(b)(h)
- Area of Square = s²
The figure is composed of a triangle and a square. Find the area of the figure.
Area of the figure = 1/2(b)(h) + s² = 1/2(5)(4) + 5² = 35 cm²
12.2% of the area of the figure = 12.2/100 × 35 = 4.27 cm²
Therefore, the area of the figure painted blue, which is 12.2% of the total area is: 4.27 cm².
