Constant is occurring continuously over a period of time so C is the correct answer because C is constant for a period of time
Answer:
any number > than -13 and less than zero
Step-by-step explanation:
Step-by-step explanation:
nobody knows!!
First, think of it as 3 different expressions.Go through them one at a time. There is:
-2a(a+b-5) ] +3(-5a+2b) ] +b(6a+b-8)
Multiply everything out.] Multiply everything out. ]Multiply everything out
-2a x a = -2a² ] +3 x -5a = -15a ] +b x 6a = 6ab
-2a x b = -2ab ] +3 x 2b = 6b ] +b x b = b²
-2a x -5 = 10a ] -15a + 2b = -15a+2b ] +b x -8 = -8b -2a² + -2ab + 10a = ] ] 6ab + b² + -8b =
-2a²+-2ab+10a ] ] <span>6ab+b²+-8b
</span>Now add everything up, but before that, remember these algebraic rules:
∞A.S.S. Add Same Signs, meaning positive add positive or negative add negative equals a positive number or 0. E.g 1+1=1 and -1+-2= 1
∞S.I.D. Subtract If Different, meaning a positive number add a negative number always equals a negative number or 0. E.g 1 + -2 = -1
∞You can only add up "similar terms", meaning you can add 'terms' ending in 'a' for example with another 'term' ending in 'a'. However. you cannot add a term ending in 'a' to an 'ab' or an 'a²'.
Following these rules, -2a²+-2ab+10a+-15a+2b+<span>6ab+b²+-8b =
</span>4ab-5a-6b+b²-2a²
Hope that helps you and that it wasn't too tricky to understand. :)
Answer:
528 sq feet
Step-by-step explanation:
Given that
The width of triangular tent is = 16 ft
The height of triangular tent is = 6 ft
Length of triangular tent is = 12ft
The measurement of side length = 10 ft
Note: figure given below can be helpful in visualizing the problem.
The material required can be calculated by calculating the area of the figure show. As we can see the two sides of our tent are rectangular and other two sides are triangular whose base (width of tent) and height is given as well.
Area of figure = 2 x Area of rectangular region of tent + 2x Area of triangle region of Tent + Area of base rectangle
Area of figure = 2x12x10 +2x0.5x16x6 + 16x12
Area of figure = 240 + 96 + 192
Area of figure = 528 squares feet
So, the material required is 528 sq feet.
