3. A regular pentagon has a perimeter of 10x + 15. What is the length of che side?
A. x+2
B. 2x-3
C. 2x + 3
D. 10(x + 2)
How do I get the answer??
Answer:
C
Step-by-step explanation:
A pentagon has 5 sides. Given that it is a regular pentagon, these 5 sides are equal.
The perimeter is the total length of all the sides of the pentagon. Since these 5 sides are all equal, we can divide the perimeter by 5 to obtain the length of a side of the pentagon.
Perimeter= 10x +15
Length of each side
= (10x +15) ÷5
= 2x +3

What does AD equal? PICTURE INCLUDED* Triangle congruence and similarity.
Answer:
AD = 7
Step-by-step explanation:
Given that the two triangles are similar by the SSS (side side side) postulate, the triangles share the same ratios when it comes to their sides.
We know the values for lines DB, EB and CB, therefore we can solve for AB, and subtract DB to find AD
We can solve the problem by solving for x:
[tex]\frac{x}{32} =\frac{21}{24}[/tex]
Cross multiply.
[tex]24x = 672[/tex]
Simplify.
[tex]x=28[/tex]
Subtract the value of DB to find AD.
[tex]28-21=7[/tex]
[tex]AD=7[/tex]

Solve: За – 6 = -12 a =
Answer:
a=−2
Step-by-step explanation:
Let's solve your equation step-by-step.
3a−6=−12
Step 1: Add 6 to both sides.
3a−6+6=−12+6
3a=−6
Step 2: Divide both sides by 3.
3a /3 = −6 /3
a=−2

Hello!
For this problem we are given that quadrilateral ABCD is congruent to quadrilateral GJIH, meaning that all sides and angle measures will be equivalent to its corresponding side.
This means that to find [tex]x[/tex], we can look at quadrilateral GJIH's corresponding side to quadrilateral ABCD's side AD, which is side GH, which has a value of 9.
This means that 9 should also be the side length of side AD, which we're given a value of [tex]x/3[/tex].
[tex]x/3=9[/tex]
Solve.
[tex]x=27[/tex]
Hope this helps!

Sobert is a frozen dessert that is often made from fruit. How many portions,each weighing 1/10 of a kilogram, can a French chef create from 3 kilograms of sober?
Answer: The number of portions French chef can create from kilograms of sober = 30
Step-by-step explanation:
Given: Weight of each portion = [tex]\dfrac{1}{10}[/tex] kilogram
The number of portions French chef can create from kilograms of sober
= (3 kilograms) ÷ [tex]\dfrac{1}{10}[/tex]
[tex]=3\div \dfrac{1}{10}[/tex]
[tex]=3\times10[/tex]
= 30
Hence, the number of portions French chef can create from kilograms of sober = 30

factorise 15 xy - 6 X + 5 Y - 2 please answer me fast who answered will mark as brainleist
Answer:
15xy-6x+5y-2
15xy+5y-6x-2
5y(3x+1) -2(3x+1)
(we pick one out of the (3x+1) brackets.
your final answer becomes:
(5y-2)(3x+1)
Answer:
(5y - 2)(3x + 1)
Step-by-step explanation:
Let's focus on those first two terms, 15xy and 6x. They have two factors in common, an x and a 3, giving them a greatest common factor of 3x. If we factor that out, the expression 15xy - 6x becomes 3x(5y - 2). Substituting that into our original expression, we get the new expression
[tex]3x(5y-2)+5y-2[/tex]
Let's group those last two terms to make our next step clearer:
[tex]3x(5y-2)+(5y-2)[/tex]
Now, each term has the factor (5y - 2) in common. We can pull it out to get the fully factored expression
[tex](5y-2)(3x+1)[/tex]

Step-by-step explanation:
The area of a parallelogram is the product of its length and height. The length of a slanted side is irrelevant. The only dimension that matters for determining area is the perpendicular distance between the edges you decide to call the "base."
In this figure, dimensions are given for the bottom (and top) parallelogram of the cuboid. The front (and back) edge is 15 cm long, and the perpendicular distance between them is shown as 3 cm.
So, the area of the bottom parallelogram is ...
A = bh
A = (15 cm)(3 cm) = 45 cm² . . . . area of the base parallelogram
__
The volume of a prism is the product of its base area (B) and its height (h) perpendicular to the base. Here, the height is shown as 12 cm. We just computed the base area, so we can now find the volume as ...
V = Bh
V = (45 cm²)(12 cm) = 540 cm³
The volume of this prism is 540 cm³.

Which expression is equivalent to sqrt 8x^7y^8? Assume x>0
Answer:
√8x^7y^8
= 2x^3y^4 √2x
answer is C. third choice
Step-by-step explanation:
The expression is equivalent to given expression is [tex]2^{\frac{3}{2} }x^{\frac{7}{2} }.y^4[/tex].
What is an equivalent expression?Equivalent expressions are expressions that work the same even though they look different. If two algebraic expressions are equivalent, then the two expressions have the same value when we plug in the same value for the variable.
The given expression is √(8x⁷y⁸).
Here, √(8x⁷y⁸)
= [tex](8x^7y^8)^{\frac{1}{2} }[/tex]
= [tex]2^{\frac{3}{2} }x^{\frac{7}{2} }.y^{\frac{8}{2} }[/tex]
= [tex]2^{\frac{3}{2} }x^{\frac{7}{2} }.y^4[/tex]
Therefore, the equivalent expression is [tex]2^{\frac{3}{2} }x^{\frac{7}{2} }.y^4[/tex].
