Answer:
432 cm²
Step-by-step explanation:
To find the surface area of a cuboid, there is a formula.
2lw+2lh+2hw
Length is l, height is h, and width is w.
2(12)(8)+2(12)(6)+2(6)(8)
Multiply all the terms.
336+96
Add both the terms.
= 432
The surface area of the open cuboid is 432cm².
Surface area = 2(12*12+15*12+15*12) = 1008
1008 * 4 = 4032
Answer:
The correct way to set up the slope formula for the line that passes through points (5 , 0) and (6 , -6) is
⇒ C
Step-by-step explanation:
The formula of the slope of a line passes through points
and 
is 
∵ The line passes through points (5 , 0) and (6 , -6)
∴
= 5 and
= 6
∴
= 0 and
= -6
Substitute these values in the formula of the slope
∵ 
∴ 
Let us look to the answer and find the same formula
The answer is:
The correct way to set up the slope formula for the line that passes through points (5 , 0) and (6 , -6) is 
44

-3x + 2 > 14.
-2 -2 -2
42

-3x > 12
-------------------------------------
-3 -3 -3 (dividing with inequalities by a negative flips the inequality symbol)
-14

x < -4
Answer:
First question the answer is the third one, 4*4*4*4*4
Second: Part A
I think one side is 25 yards, so answer is 25². that makes the area of the chicken pen to be 625 sqaure yards.
Part B a yard is exactly three feet, so the power becomes 75², and the area is 5625 square feet.
third question: not sure what the only use once is, but 2^4 and 4² could be the first one, they both equal 16. The second could be 3^4 and 9^2, which are both 81.
