The word equiangular means that all the angles of the figure are equal. Further, equilateral means that all the measures of its sides are also equal. From the given above, only a square is both equiangular and equilateral. Thus, the answer is letter B.
Answer:
what do you mean it's not 7 it is 7
Step-by-step explanation:
The value of x is 7
The given parameters are:
\angle BAE = 9x + 2∠BAE=9x+2
\angle BAD = 130^o∠BAD=130
o
Line AE is the angle bisector of \angle BAD∠BAD
This means that:
\angle BAD = 2 \times \angle BAE∠BAD=2×∠BAE
So, we have:
130 = 2 \times (9x + 2)130=2×(9x+2)
Divide both sides by 2
65 = 9x + 265=9x+2
Subtract 2 from both sides
63 = 9x63=9x
Divide both sides by 9
7 = x7=x
Rewrite as:
x = 7x=7
Hence, the value of x is 7
Answer:
Step-by-step explanation:
calculate :
f(-1) =3(-1)-5 = - 8
f(5) =3(5)-5 = 10
f(2) =3(2)-5 = 1
f(4) =3(4)-5 = 7
the range is : E = {-8.10,1,7}
Answer:
x < 11
Step-by-step explanation:
35 > -5(4 - x)
35 > -20 + 5x
55 > 5x
x < 11

You have to make 2 equations
185 = 2(x) + y
X is the hours and y is the setup fee
315 = 4(x) + y
Now you solve the first
185 = 2x+y
185-y = 2x
(185-y)/2 = x
That means you can plug that value into the second equation where you see the x
315 = 4((185-y)/2) + y
315 = 370-2y + y
315 = 370 - y
-55 = - y
55 = y
So y is 55 (the setup fee)
Back to the original
185 = 2(x) + y
185 = 2(x) + 55
130 = 2x
65 = x
Now test it
575 = 8x + y
575 = 8(65) + 55
575 = 520 + 55
575 = 575
