Answer:
8
Step-by-step explanation:
we can say that AD is congruent to DC
so your equation for x is: 4x - 1 = 2x
solve this to get x = 0.5
plug x into and equation and multiply you answer by 2 to find the hypotenuse of triangle ABC and DEF
4(0.5) - 1 = 1
hypotenuse: 1 x 2 = 2
since we know x is 0.5, plug this into 4x + 1 to find the length of the leg FE,
4(0.5) + 1 = 3
In the diagram, it shows that the legs of triangle are congruent
this means that FE, ED, BA, and BC are all congruent
since we know FE is 3, we know that all the other sides are 3 as well
this means that the perimeter of the triangle is: leg + leg + hypotenuse
so 3 + 3 + 2
the perimeter is 8
Answer:
4/8, 1/2
Step-by-step explanation:
7/8 - 3/8 = 4/8
4/8 >>> divide both by 4
4 divided by 4 = 1
8 divided by 4= 2
1/2 Inches

Answer:
7k
____________________________________________________
Step-by-step explanation:
We are trying to combine like terms with the expression: -k - ( - 8k)
We are pretty much solving it.
Solve:
-k - ( - 8k)
The "- ( -" turns into a plus sign.
So it would look like:
-k - -8k or -k + 8k
Now, you would finish solving
-k + 8k = 7k

Answer:
-3
Step-by-step explanation:
Bring -2 to the other side and A to the other side
<em>-</em><em>2</em><em> </em><em>Become </em><em>2</em><em> </em><em>because </em><em>of </em><em>flipping</em>
<em>And </em><em>A </em><em>becomes </em><em>-A </em><em>because </em><em>of </em><em>flipping</em>
<em>2</em><em>-</em><em>2</em><em>+</em><em>3</em><em>=</em><em>-A</em>
<em>Flip </em><em>the </em><em>whole </em><em>equation </em><em>to </em><em>avoid </em><em>confusion</em>
<em>-A=</em><em>2</em><em>-</em><em>2</em><em>+</em><em>3</em>
<em>-</em><em>A=</em><em>+</em><em>3</em>
Bring the minus sign to the other side,
<u>A=-3</u>
<u>-</u><u>3</u><u> </u><u>-</u><u>2</u><u> </u><u>+</u><u>3</u><u> </u><u>=</u><u> </u><u>-</u><u> </u><u>2</u>
<u>Which </u><u>make </u><u>the </u><u>statement</u><u> </u><u>correct.</u>
<u>I hope </u><u>this </u><u>explanation</u><u> </u><u>helps, dont hesitate to ask for any question.Mark me as brainliest is appreciated.Tq!!</u>
