Answer:
This is a rectangle, so if AB is equal to 3 centimeters, then DC is equal to 3 centimeters.
Since Angle X is equal to 45 degrees, then angle CDE, is also equal to 45 degrees, and we have an isosceles triangle, since angle CDE and DEC are equal to each other.
This means, that CE = DC.
And because E is the midpoint of CB, CE = EB.
So basically, we have:
DC = CE = BE
DC = 3
3 = CE = BE
And we see that CE and BE are both equal to 3, which makes CB equal to 6, which makes solving the area easy. (3 x 6), which is 18.
B is correct!

x = 1.4 or -1.4
Step-by-step explanation:
→ Substitute y = 4 into y = x² + 2
4 = x² + 2
→ Minus 2 from both sides
2 = x²
→ Square root both sides
√2 = x
→ Simplify
x = 1.4 or -1.4
Using the GCF and distributive property, which expressions is equivalent (equal) to 12y + 16
A 2(6y + 80)
B 4(3y + 4)
C 28y
D 16 + 12y
Answers
Answer:
4(3y+4)
Step-by-step explanation:
12y + 16
4*3*y +4*4
Factor out 4
4(3y+4)
Answer:
2(6y+80) = 12y+160
4(3y+4) = 12y+16
28y = 28y
16+12y = 12y+16 (did not use distributive property)
So, B is correct.

180$ simple unless u have a different way to do it
Answer:
y=15x+25, the cost is 205 dollars
Step-by-step explanation:
The simplest way to write a rule for this is to write it in slope intercept form, y=mx+b. Let y represent the cost of the membership. Every month the cost is 15 dollars. If we let x represent the months we can rewrite this as 15x. The one time cost is 25 dollars so we can just add that to the end of the equation. y=15x+25. There are 12 months in a year so we just have to substitute. y=15(20)+25=205 so the answer is 205 dollars.

Answer:
2^-1
Step-by-step explanation:
2^2 *2 / 2^4
We know that 2^2 * 2 = 2^2 *2^1
a^b*a*c = a^(b+c) so 2^2*2*1 = 2^(2+1)+ 2^3
2^3 / 2^4
We know that a^b / a^c = a^(b-c)
2^3 /2^4 = 2^(3-4) =2^-1

Let us first multiply out the numerator to get;
2² × 2 = 2³
Thus, our overall expression is;
2³/2⁴
According to laws of exponents;
a^(b)/a^(c) = a^(b-c)
Thus;
2³/2⁴ = 2³⁻⁴

Answers
Answer:
You can check if an equation is true for all some or no values of x by simply to try and solve the equation if you get something like x = x, then the equation is true for all, if you get a specific answer like x=3, then it is true to some values, in simple terms. Try and solve the equation there is no other way to check unless you solve, I don't know if there is another way but this is just my intution.

My neighborhood is full of one-way streets. To drive from my house to the grocery store, I have to go 1 block south, then 1 block east, then 5 blocks north, then 2 blocks east. Each block is 1/16 of a mile. How much shorter would my trip be if I could fly like a bird (that is, travel in a straight line)?
I FOUND THE distance for non bird which is 9/16. I wanna apply the pythagoreum theorum and draw a straight line to make it a triangle so I can do so but don't know where to place it
Answers
Answer:
1/4
Step-by-step explanation:
1 block south from here puts you at (0, -1/16)
1 block east from here now puts you at (1/16, -1/16)
5 blocks north from here puts you at (1/16, 4/16)
2 blocks east from here puts you at (3/16, 4/16)
You have traveled (1/16) ( 1 + 1 + 5 + 2) = 9 / 16 of a mile
The "straightline" distance between (0, 0) and (3/16, 4/16) =
sqrt [ (3/16^2 + (4/16)^2 ] = sqrt [ 25 / 256] = 5/16 of a mile
Your trip would be { 9/16 - 5/16 } equals 4/16 and simplifies equals 1/4 of a mile.
