Answer:
C. 128 in²
Step-by-step explanation:
We know that the opposite sides of rectangles are congruent, so 8 = 2x. If we divide 8 by 2 and 2x by 2, we get x = 4.
- This means that the other side length, (3x + 4), equals 3(4) + 4 = 12 + 4 = 16 inches
Now, the area of a rectangle is l × w, where l = length and w = width. The dimensions of this rectangle are 8 and 16, so 8 × 16 = 128 in².

Answer:
Step-by-step explanation:
The triangle KLM is shown in the attached photo. The sum of the angles in a triangle is 180 degrees. It means that
angle K + angle L + angle M = 180 degrees. Since
m angle K=(10x+10). m angle L=(9x-3). m angle M=(7x-9), then
10x + 10 + 9x - 3 + 7x - 9 = 180
10x + 9x + 7x = 180 + 9 + 3 - 10
26x = 182
x = 182/26
x = 7
m angle K=(10x+10) = 10×7 + 10 = 80 degrees
m angle L=(9x-3) = 9×7 - 3 = 60 degrees
m angle M=(7x-9) = 7×7 - 9 = 40 degrees.
The triangle is an acute triangle because each angle is lesser than 90 degrees
The triangle is scalene triangle because non of the sides are equal.
If you do 5907/7 you will get 843.85714
Do 843*7=5901.
Then do 5907-5901=6
The final answer you will get is 6.
First multiply C by F by multiplying each row in C by each column in F:
12 * -2 + 0*0 + 1.5*2 12*0 + 0*8 + 1.5*1
1*-2 -6*0 +7.2 1*0-6*8 +7*1
to get a matrix of:
-21 1.5
12 -41
Now subtract that matrix from B:
2- -21 = 2+21 = 23
8 - 1.5 = 6.5
0.6 - 12 = -11.4
3 - -41 = 3+41 = 44
So you have:
23 6.5
-11.4 44
Which makes C the correct answer.
