The answer for this question will be A !! I might be wrong and I’m sorry but I’m saying A
Answer:
c = -9
Step-by-step explanation:
- 4c + 25 + c = 3c + 79 Combine like terms.
- 4c + c + 25 = 3c + 79
- 3c + 25 = 3c + 79
- 3c + 3c + 25 = 3c + 3c + 79
25 = 6c + 79
25 - 79 = 6c + 79 - 79
- 54 = 6c
-54/6 = 6c/6
-54/6 = c
-9 = c
There aren't 2 answers, you could have 2 answers if one of the c's was squared. Here is another way to do the math.
- 4c + 25 + c = 3c + 79
- 4c + c + 25 = 3c + 79
- 3c + 25 = 3c + 79
- 3c - 3c + 25 = 3c - 3c + 79
- 6c + 25 = 79
- 6c + 25 - 25 = 79 - 25
- 6c = 54
- 6c/- 6 = 54/- 6
c = 54/- 6
c = - 9
5) i dont know
6) (6x-5)(3x-4)
<u>Complete Question</u>
Which could be the area of one face of the triangular prism? Select three options.
A triangular prism. The rectangular sides are 12 by 10, 12 by 8, and 12 by 6. The triangular sides have a base of 8 and height of 6.
- 24 square units
- 48 square units
- 72 square units
- 96 square units
- 144 square units
Answer:
(A)24 square units
(C)72 square units
(D)96 square units
Step-by-step explanation:
<u>For one Triangular face</u>
- Height=6 Units
- Base =8 Units
Area of the Triangular Face =0.5 X 6 X 8=24 Square units
<u>Area of the rectangular Faces</u>
Area of Rectangular face with dimension 12 by 10=12 x 10=120 Square Units
Area of Rectangular face with dimension 12 by 8= 12 X 8=96 Square Units
Area of Rectangular face with dimension 12 X 6=12 x 6=72 Square Units
Therefore, from the options, the possible areas are:
(A)24 square units
(C)72 square units
(D)96 square units
