Answer:
Surface area is 300 in Squared
Step-by-step explanation:
2(lw + wh + hl) = rectangular Prism Formula
Length- 12
Width- 9
Height- 2
So just Substitute the values.
2( 12 x 9+ 9 x2 + 12 x 2) = ?
2(108 +18+ 24)
2 x 150
= 300
1/2 (14x-2)-1/4(4x-24) = 6x + 5
Answer:
Option a is correct.
The rotation for the transformation to △A'B'C' is , rotation of 90 degree.
Explanation:
In △ABC
The coordinate of point A = (1,1) , B = (3,1) and C = (1,4).
Rotate triangle ABC 90 degree's around the origin;
The rule for this transformation is:- (x,y) to (-y ,x)
A(1,1) to A' (-1,1) ,
B(3,1) to B'(-1 , 3) and
C(1,4) to C' (-4,1)
therefore, rotation of 90 degree counter clockwise rotation around the origin results in the transformation of △ABC to △A'B'C'
Answer: C: (x+6)(x-2); 84 square feet.
Step-by-step explanation:
it says that the length of hallway is 6 feet longer than 8 feet i.e 14 feet and width is 2 feet shorter that 8 feet i.e 6 feet.
so the the area will be
so the area of hallway be 14 x 6 i.e 84
and the area of square 8 x 8 i.e 64
