Answer:
x = 13
Step-by-step explanation:
5x + 25 must equal 7x - 1, because all of the angles in the figure are right angles.
Then 5x + 25 = 7x - 1, and
25 = 2x - 1, and so 2x = 26 and x = 13
Step-by-step explanation:
1.8×10 to the power of 8
8.0×10 to the power of 6
1.2 ×10 to the power of 6
2.4×10 to the power of 2

C
Step-by-step explanation:
Answer:
x = 4
Step-by-step explanation:
<em>Perimeter of triangle = sum of all sides</em>
Side 1: 14 - 2x
Side 2: 3x - 1
Side 3: 2x + 1
<em>Perimeter= side 1 + side 2 + side 3</em>
26 = 14 - 2x + 3x - 1 + 2x + 1
26 = 14 - 1 + 1 - 2x + 3x + 2x
26 = 14 + 3x
3x = 12
x = 12/3
x = 4
