Step-by-step explanation:
<u>Step 1: Define</u>
-84 = -2(2 + 5k)
<u>Step 2: Solve for </u><em><u>k</u></em>
- Divide -2 on both sides: 42 = 2 + 5k
- Isolate <em>k</em> term: 40 = 5k
- Isolate <em>k</em>: 8 = k
- Rewrite: k = 8
<u>Step 3: Check</u>
<em>Plug in k into the original equation to verify it's a solution.</em>
- Substitute in <em>k</em>: -84 = -2(2 + 5(8))
- Multiply: -84 = -2(2 + 40)
- Add: -84 = -2(42)
- Multiply: -84 = -84
Here we see that -84 does indeed equal -84.
∴ k = 8 is the solution to the equation.
Answer:
1.first add 5, then 8 then 11, then 14 so it goes 3 by 3
3. you add 25 each time
4. you add 9 each time
I couldn't solve second and fifth one
Answer:
x=110
Step-by-step explanation:
The exterior angle is equal to the sum of the opposite interior angles
45+65 = x
110 =x
3x-6+9+5=25 is the first step
X=52
so when finding the area of the square, 46x52=2392
than when finding the area of the triangle, 26x46=1196
than add 2392 and 1196 and u should get: 3588
So the area for the picnic tables is 1196
