Answer:
Step-by-step explanation:
Given the expression (x+11)(2x+3)
We want to expand it and write equivalent expression
Generally if we want to expand an expression we will take one of the expression in one bracket and multiply with the other bracket and then take the other expression and multiply it with the other
E.g, (a+b) × (c + d)
Then, we take a × (c+d) and also b × (c+d)
We can do it the other way round too and it will give the same results.
So, applying this to the given expression
(x+11)(2x+3)
x(2x+3) + 11(2x+3)
2x² + 3x + 22x + 33
2x² + 25x + 33
Then, the equivalent expression is 2x² + 25x + 33
(x + 11)(2x + 3) = 2x² + 25x + 33
The quadratic formula is -b plus minus the square root of b^2-4ac all over 2a.
Here, a=1, b=13, and c=30.
The only option that fills in the values correctly is D
Answer:
C
Step-by-step explanation:
There are three turning points.
The local minimums are (-1,-5) and (1, -5)
The local maximum is (0,-4)
Answer:
It is right
Step-by-step explanation:
Because the hypotenuse must be greater than all the legs, we have that
is the hypotenuse. So, we want to determine if
.

This means the triangle is indeed right!
52 by multiplyong 13*4 you get 52 as ur answer
