The side length of an equilateral triangle is 4X +2 which expression represents the perimeter of the triangle
Answer:
12x + 6
Step-by-step explanation:
perimeter equals the sum of all sides
if each side is 4x+2 then 3(4x+2) = 12x+6

16
Step-by-step explanation:
the sides may not seem to help but it dose go to the other side and try to meser it it would be 4. add 8+4+4 or 8+8=16
Answer:
18.6cm (rounded to 3 s.f.)
Step-by-step explanation:
You can actually figure out the two bases of the triangles based on the Pythagoras theorem where the slant length of a 90° triangle is [tex]\sqrt{a^{2} + b^{2} }[/tex] where a is one of the bases and b is the other length that is 90° perpendicular to a.
So this means:
[tex]\sqrt{6^{2} + base^{2} }[/tex] = 8cm
6² + base² = 64cm
36 + base² = 64
base² = 64-36
= 28
base = [tex]\sqrt{28}[/tex]
≈ 5.2915 (5 s.f.)
So the two bases are roughly 5.2915, and the middle base is part of a rectangle, so it has the same length as the rectangle's length, which is 8cm.
Thus, x = 5.2915 + 5.2915 + 8
= 18.6cm (rounded to 3 s.f.)

Is a²b the same thing as ba² ?
Please explain. Thanks so much!
a²b is the same thing as ba²
b and a are two separate variables lets pretend a is 2 and b is 3
2² * 3 = 4 * 3 = 12
3 * 2² = 3 * 4 = 12
this is the commutative property of multiplication
An expression is defined as a set of numbers, variables, and mathematical operations. The two of the given expressions a²b and ba² are the same.
What is an Expression?In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.
The two of the given expressions a²b and ba² are the same because if the two of the expressions are expanded then the value of the two expressions will be equal to each other.
Therefore, the two expressions are expanded as shown below,
a²b = a × a × b
ba² = b × a × a
Therefore, the two of the given expressions a²b and ba² are the same.

Megan's room was remodeled. The new area of the room is 175% of the previous area. Only the length of the room changed. The width of the original room is 4m and the length of the original room is 4m. If the new room adds X to the length, what is the new expression for the new area? How many square meters has Megan's room increased? Explain how you solved the new area.
Answer:
new area = 7m (length) x 4m (width) = 28; an increase of 12 sq meters
Step-by-step explanation:
Original area must have been 16 because both the length and width were 6 meters.
175% of 16 is 12, meaning the length must be increased from 4 to 7 to get 28 when multiplied by a width of 4m

Predict if the product will be greater than, less than or equal to the second factor 4/5 x 1 2/5 = y
Answer:
The product will be less than the second factor.
Step-by-step explanation:
Given the expression
[tex]\frac{4}{5}\:\times \:1\frac{2}{5}\:=y[/tex]
solving to determine the product value
[tex]y=\:\frac{4}{5}\times \:\:1\frac{2}{5}[/tex]
[tex]=\frac{4}{5}\times \frac{7}{5}[/tex]
[tex]\mathrm{Apply\:the\:fraction\:rule}:\quad \frac{a}{b}\times \frac{c}{d}=\frac{a\:\times \:c}{b\:\times \:d}[/tex]
[tex]=\frac{4\times \:7}{5\times \:5}[/tex]
[tex]=\frac{28}{5\times \:5}[/tex]
[tex]=\frac{28}{25}[/tex]
As the value of the second factor is:
[tex]1\frac{2}{5}=\frac{7}{5}=1.4[/tex]
And the product value is:
[tex]y=\frac{28}{25}=1.12[/tex]
It is clear that the product value 'y = 1.12' is lesser than the second factor value '1.4'.
i.e. 1.12 < 1.4
Thus, the product will be less than the second factor.

To solve the equation for x, first divide both sides of the equation by 4 to get [tex]e^{2.7x}=\frac{33}{4}[/tex]. Then, take the natural logarithm of both sides (base e) to get [tex]\ln e^{2.7x} = \ln (33/4)[/tex]. The left hand side of this equation if equal to 2.7x, so we get [tex]2.7x = \ln(33/4)[/tex]. The final step is to divide both sides of the equation by 2.7, to get that [tex]x =\frac{ \ln (33/4)}{2.7}[/tex]. This is approximately equal to 0.782.
