There are four terms in that expression.
Answer:
1890.75!
Step-by-step explanation:
You can write out the equation like so: t = 2(d) and the dvd costs d. So, d + 2d = 1296. Which is also 3D=1296. So divide 1296/3 to solve for the cost of the DVD player = 432 and the cost of the tv is 2(d) or 2 x 432 = 864.
1.44ft2. I worked it out on paper and that is what came out of the problem
You need to know the rule or theorem for the lengths of the sides of a triangle,which is: the lengths of any two sides of a triangle must add up to more than the length of the third side.
So, let's examine each option:
<span>A.4 inches => side A: 7, side B: 11, side C: 4 ---> NOT POSSIBLE
Justification:
7 + 4 = 11
11 = 11 => the sum of sides A and C is not greter than the side B, so it does not satisfy the rule.
B. 7 inches => side A: 7, side B: 11, side C: 7. ---> COULD BE
Justification:
7 + 7 = 14; 14 > 11
7 + 11 = 18; 18 > 7
C. 13.5 inches => side A: 7, side B: 11, side C: 13.5: ---> COULD BE
Justification:
7 + 11 = 18; 18 > 13.5
7 + 13.5 = 20.5; 20.5 > 11
11+13.5 = 24.5; 24.5 > 7
D. 18 inches => side A: 7, side B: 11, side C: 18 ---> NOT POSSIBLE
Justification:
7 + 11 = 18; 18 = 18 => it does not satisfy the rule.
E. 20 inches
=> side A: 7, side B: 11, side C: 20 ---> NOT POSSIBLE
Justification:
7 + 11 = 18; 18 < 20 => it does not satisfy the rule</span>
