Answer:
22 square units.
Step-by-step explanation:
The missing image is attached.
We want to find the area of the figure shown in the attachment.
We can quickly calculate the area of the figure by counting the unit squares.
Counting from top row, we have: (6 +4+6+3+3) unit squares.
This simplifies to 22 unit squares.
Answer:
Option (3) is correct.
The zero of given function is x= -1 and x= -3.
Step-by-step explanation:
Consider the given function
We need to find the zero of the above function. Put f(x)=0
then ,
The above function represents a quadratic equation
We can solve the quadratic equation by splitting middle term method,
We can write 4x as x+ 3x ,
or
or
Thus, the zero of given function is x= -1 and x= -3.

Answer:
42 w^6 y^9
Step-by-step explanation:
Simplify the following:
3×7×2 w^5 y^7 y^2 w
3 w^5 y^7×7 y^2×2 w = 3 w^(5 + 1) y^(7 + 2)×7×2:
3×7×2 w^(5 + 1) y^(7 + 2)
7 + 2 = 9:
3×7×2 w^(5 + 1) y^9
5 + 1 = 6:
3×7×2 w^6 y^9
3×7 = 21:
21×2 w^6 y^9
21×2 = 42:
Answer: 42 w^6 y^9
Substitute the value of x = -2 to the inequalities:
-3x < 1
(-3)(-2) < 1
6 < 1 FALSE
x - 7 < -4
-2 - 7 < -4
-9 < -4 TRUE
-12/x > 10
-12/(-2) > 10
6 > 10 FALSE
x + 7 > 5
-2 + 7 > 5
5 > 5 FALSE
Answer: x - 7 < -4
