Solution:
<u>We know that:</u>

<em>Since we are already given the base and the height, we can substitute them into the formula to find the area of the triangle.</em>

<u>Cancel out the "2" by dividing it by 18.</u>

<u>Simplify the multiplication.</u>

3.305
+1.7
5.005
Line up the decimal points and add like you usually would add.
5.005 is the answer.
He have about 0 dime and 69 coins each
Answer:
D, E, C, A, and B.
Step-by-step explanation:
We wish to solve the equation:

Let’s go through this step-by-step.
1) Distributive Property:

2) Commutative Property of Addition (we rearrange them):

3) Combined Like Terms:

4) Addition Property of Equality* (we add <em>-1</em> to both sides):

5) Multiplication Property of Equality (we multiply both sides by -1):

So, our sequence is:
D, E, C, A, and B.
*A better choice would’ve been the Subtraction Property of Equality, but both are equally fine.
Answer:
Value of x using quadratic formula (x = -4) and (x = -5)
Step-by-step explanation:
Given:
Equation
x² + 9x + 20 = 0
Find:
Value of x using quadratic formula
Computation:
Quadratic formula = [-b±√b²-4ac] / 2a
Given equation;
x² + 9x + 20 = 0
a = 1 , b = 9 , c = 20
By putting value
[-9±√9²-4(1)(20)] / 2(1)
[-9±√81-80] / 2
[-9±√1] / 2
(-9 + 1) / 2 , (-9 - 1) / 2
-8 / 2 , 10 / 2
-4 , - 5
Value of x using quadratic formula (x = -4) and (x = -5)
