Answer:
figure a.n
Step-by-step explanation:
alright what I'm fixing to explain is very important so listen closely....
Area = length x width
Area = 21 square cm
Width = x
Length = 3x + 2
21 = 3x+ 2 * x
21 = 3x ^2 + 2x
Subtract 21 from both sides:
3x^2 + 2x -21 = 0
Use the quadratic formula to solve for x:
-2 +/- sqrt(2^2-4*3(-21))/(2*3)
X = 7/3 and -3
A dimension can’t be a negative value so x needs to be 7/3
Width = x = 7/3 = 2 1/3 cm
Length = 3(7/3) + 2 = 9 cm
Check: 9 x 2 1/3 = 21
Dimensions: width 2 1/3 cm length 9 cm
Answer:
6
Step-by-step explanation:
Maybe you want a suitable common denominator for 2/3 and 1/6. If so, you can observe that 3 is a factor of 6, so 6 is a suitable common denominator.
2/3 = (2/3)·(2/2) = (2·2)/(3·2) = 4/6
The equivalents, 4/6 and 1/6, share a common denominator of 6.
Answer:C
Step-by-step explanation:
24/6=4
P6R2/ P2Q2R6
Cancel you have P4 left on top
Cancel you have R4 left on bottom
Q2 stays at bottom
Answer:
According to the question z must be equal to 4. So value of a+b=z or a+b=4
Lets try each of the options
A) a+b
1.6+2.3=3.9 which is not equal to 4
So option a is not the asnwer.
B) a+b = 1.6+2.5= 4.1 which is not equal to 4
<em>C) a+b= 1.9+2.1= 4.00 which is equal to 4</em>
<em />
D) a+b= 2.1+3.4= 5.5 which is not eqaul to 4
<u>Thus, we have OPTION C AS THE CORRECT ANSWER</u>
