Answer:
x = 7, x = -3
Step-by-step explanation:
We can find the zeros by factoring the equation using the zero product property.
x^2-4x-21 = 0
(x-7)(x+3) = 0
<u>x-7 = 0</u>
x = 7
<u>x+3 = 0</u>
x = -3
Zeros are x=7 and x= -3.

Answer:
b < 11 = The baby weighs at least 11 pounds.
b > 11 = The box contains more than 11 books.
b < 12 = There are fewer than 12 beetles in a jar.
b > 12 = The building is taller than 12 feet.
Step-by-step explanation:
The baby weighs at least 11 pounds is b < 11 because the baby weighs more than 11 pounds.
The box contains more than 11 books is b > 11 because there are more books in the box than 11.
There are fewer than 12 beetles in a jar is b < 12 because there are less than 12 beetles in a jar.
The building is taller than 12 feet is b > 12 because 12 feet is less than how tall the building is.
Base of parallelogram b = 24.5 cm
Step-by-step explanation:
We are given:
Perimeter =P= 63 cm^2
Slant Height =a= 7 cm
Base of Parallelogram =b= ?
The formula used is:

where a is height and b is base
Putting values:

So, Base of parallelogram b = 24.5 cm

Answer:
-40 feet
Step-by-step explanation:
To answer this problem is really simple
you take -32 and add 5. This gets you -27
The next thing to do add -13 to -27. This gets you -40.
