b 35
Step-by-step explanation:
you need to find it between the two middle numbers 30 and 40
which gives you 35
Answer:
length of each edge = (x + 3)
Step-by-step explanation:
The surface area of each face of the cube = (
+ 6x + 9) 
. But the surface of a cube has the shape of a square. So that,
Area of a square = length x length
= 
By factorizing the area,
+ 6x + 9 = + 3x + 3x + 9
= ( + 3x) (3x + 9)
= x(x +3) + 3(x + 3)
= (x + 3)(x + 3)
= 
+ 6x + 9 =
Thus,
=
find the square root of both sides
l = (x + 3)
length of each edge = (x + 3)
I hope you find the answer!!
Answer:
(-1, -2)
Step-by-step explanation:
-9x= 5 - 2y
15x = -11 + 2y => 2y = -11 - 15x
Plug the value for 2y into the first equation.
-9x = 5 - 15x - 11. Solve for x.
-9x = -6 - 15x.
-9x + 15x = -6.
6x = -6.
x = -1.
Now that we found x, we will solve for y.
2y = -11 - 15(-1)
2y = -11 + 15
2y = -4
y = -2.
Thus, our solution set is (-1, -2).
Hope this helps!
Answer:
6
Step-by-step explanation:
Step 1: Multiplying the power
2 x 2 x 2 = 8
Step 2: Subtracting:
15-8 = 7
