Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify</em>
7 - 6y - 5x³ - 1 + x³ - 7 - 2y
<u>Step 2: Simplify</u>
- [Addition] Combine like terms (x³): -4x³ + 7 - 6y - 1 - 7 - 2y
- [Subtraction] Combine like terms (y): -4x³ - 8y + 7 - 1 - 7
- [Subtraction] Combine like terms: -4x³ - 8y - 1
For these types of algebra problems, you're trying to get whatever they tell you by itself on one side of the equals sign, meaning that you have to move everything else over by adding/subtracting or whatever else.
In this problem you have to get s by itself. All you do is just subtract 4r from both sides to get:
-2 - 4r = s
Because there are 2 variables/unknowns (s and r) you have no way of actually solving this problem without having a 2nd equation or something. So thats all you can do
The answer should be 227 ft
Angle c and angle d are congruent. Congruent means they have the same the measure, or they have EQUAL measures. You set the two values equal to each other and solve for x.
X+26=2x-10 subtract x from both sides
26=x-10 add 10 to both sides
36=x
Now substitute x back in for angle d.
2(36)-10 = 62
