Answer:
D.
Step-by-step explanation:
Bottom of the ladder is base, a = 3 ft
Top of the ladder from the ground is the perpendicular, b = 4 ft
We have to find the length of ladder, c = ?
So we'll use Pythagoras theorem
c² = a²+b²
c² = 3²+4²
c² = 9+16
c² = 25
Taking square root on both sides, we'll get
c = 5 feet
The surface area of the triangular prism shown below is 186 cm²
<h3>What is an
equation?</h3>
An equation is an expression that shows the relationship between two or more numbers and variables.
An independent variable is a variable that does not depends on other variable while a dependent variable is a variable that depends on other variable.
The surface area of prism = 2(9 cm * 7 cm) + (6cm * 9 cm) + 1/2(2 cm * 6 cm) = 186 cm²
The surface area of the triangular prism shown below is 186 cm²

1/6 = 1
4 = x
4 = 1/6 * x
4 ÷ 1/6 = x
24 = x
So using 4 cups of icing you could ice 24 cupcakes
Answer:
The answer to your question is
a) 400
b) The function has two real solutions (-2 and 8)
Step-by-step explanation:
Process
1.- Discriminant = b² - 4ac
= 12² -4(-2)(32)
= 144 + 256
= 400
2.- Solutions (using the general formula)
x = 
x = 
x = 
x₁ = 
x₂ = 
This function has two real solutions (-2, 8)
