Answer:
x + 6x+10 + x+2 = 180
x = 21
Step-by-step explanation:
The sum of the angles of a triangle add to 180 degrees
x + 6x+10 + x+2 = 180
Combine like terms
8x + 12 = 180
Subtract 12 from each side
8x+12-12 = 180-12
8x =168
Divide each side by 8
8x/8 = 168/8
x =21
2 2/3 as a decimal is 2.66666667. 60 divided by 2.66666667 is 22.5.
As a fraction, the answer will be 22 5/10

Answer:
option C. Defined, 3 x 3
Step-by-step explanation:
The order of matrix A is 3 x 2 i.e 3 rows and 2 columns
The order of matrix B is 2 x 3 i.e. 2 rows and 3 columns
Two matrices can be multiplied if and only if the number of columns of 1st matrix is equal to the number of rows of 2nd matrix. Since the number of columns in matrix A is equal to the number of rows in matrix B, the product AB is defined.
The product AB will have number of rows equal to the rows of 1st matrix i.e. matrix A and number of columns equal to the columns of 2nd matrix i.e. matrix B.
So the order of AB will be 3 x 3 .
Therefore, the correct answer is option C. Defined 3 x 3
Answer:
= 
−7x−20
Step-by-step explanation:
(2x−5)(3x+4)
= (2x+−5)(3x+4)
= (2x)(3x)+(2x)(4)+(−5)(3x)+(−5)(4)
= +8x−15x−20
= −7x−20
