Answer:
f(-1) = -6
Step-by-step explanation:
[tex]f(x) = (x+2)^{2}-6[/tex] for [tex]x\neq -1[/tex]
[tex]f(x) = -6[/tex] for x = -1
f(-1) means x=-1, so we can't use the first expression.

Which is greater, 4 4/10 or 32/10? Explain how u know.
Answers
Answer:
4 4/10
Step-by-step explanation:
Well, 32/10 would by 3 2/10 when you divide it, I think. So 4 4/10 is greater.
Fractions may be equal or unequal.
[tex]\mathbf{4\frac{4}{10}}[/tex] is greater than [tex]\mathbf{\frac{32}{10}}[/tex]
The fractions are given as:
[tex]\mathbf{F_1 = 4\frac{4}{10}}[/tex]
[tex]\mathbf{F_2 = \frac{32}{10}}[/tex]
Express the fractions as improper fractions
[tex]\mathbf{F_1 = \frac{44}{10}}[/tex]
Both fractions have the same denominator.
So, the fraction with a greater numerator is greater.
By comparison: 44 is greater than 32
i.e. 44 > 32
Hence, [tex]\mathbf{4\frac{4}{10}}[/tex] is greater than [tex]\mathbf{\frac{32}{10}}[/tex]

What lever has resistance between the axis (fulcrum) and the force (effort)? A. first B. second C. third D. fourth Please select the best answer from the choices provided. A B C D
Answers
Answer:
B. Second
Step-by-step explanation:
Levers are defined as the simple machine, which consists of a rod fixed at a pivot, load, and fulcrum. The levers are classified into first class, second, and third class.
What is lever?A lever is a simple machine made of a rigid beam and a fulcrum. The effort (input force) and load (output force) are applied to either end of the beam. The fulcrum is the point on which the beam pivots. When an effort is applied to one end of the lever, a load is applied at the other end of the lever.
here, we have,
The difference between different types of levers are:
1. In the first-class levers, the fulcrum is present between the load and effort. The mechanical advantage can be greater, less, or equal to 1.
2. The second class levers, the load is present between the fulcrum and effort. The mechanical advantage is always greater than the 1.
3. The third class levers, the effort is present between the fulcrum and load. The mechanical advantage is always less than 1.
Thus, the correct answer is Option 1.

Answer:
area = x(3x +10)
Step-by-step explanation:
The lengths of the unmarked sides are found as the difference between the lengths of the parallel marked sides.
horizontal unmarked = (2x+15) -x = x +15
vertical unmarked = (2x -5) -(x -5) = x
The area of the figure is the sum of the areas of parts of the figure. The area can be divided several ways. One is shown in the attachment, along with the areas of the parts and of the whole.
The whole area is ...
x(2x -5) +x(x +15) = x((2x -5) +(x +15)) = x(2x -5 +x +15) = x(3x +10)
