Factored form is (4x+3)(2x+3)
B) 1197 Cubic Ft.
Explanation: You have to make 13 and 10 to the power of 3. 13^3 = 2197 and 10^3= 1000. Then you subtract and get 1197
The orientation of the ladder with the wall forms a right triangle. The ladder length is the hypotenuse of the triangle, the distance between the ladder at ground level and the base of the wall is the horizontal leg of the triangle, the height of the ladder is the vertical leg of the triangle.
Since we have a right triangle, we can use the Pythagorean theorem.
Let x = the height of the ladder
Write the equation for the Pythagorean theorem using the information.
x2 + 162 = 232
Solving for x, we have
x2 = 232 - 162
x = √(232 - 162)
x = √(529 - 256)
x = √(273)
x = 16.52
The ladder reaches 16.52 feet high.
Answer:

Step-by-step explanation:
Hello
When you have two negative symbols, you have to multiplied them, so:
-*-= +
+*+= +
+*-=-
-*+ = -
You can to do more research lookin this: "Algebraic operations with symbols" or "The sign´s law"
I attached a illustrative image about this.
Then,
5 - (-4) <em>(here is with -*- )</em>
5 + 4
9
