Answer:The answer is 3 & 7
Step-by-step explanation:3 x 7 = 21
3 + (7) = 10
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 + 10x + 21 = 0
If so, the solution to factor the quadratic equation above is:
(X + 3 ) (X + 7)
To summarize, since 3 and 7 multiply to 21 and add up 10, you know that the following is true:
x2 + 10x + 21 = (X + 3 ) (X + 7)

54 units²</h2><h2 />
This is a compound shape. You can split it into x shapes. See Attachment
Area of a Rectangle = L × B
L = 7
B = 6
7 × 6 = 42
<h3>42 units²</h3>
Area of a Triangle = 1/2BH
B = 6
H = 1
1/2 × 6 × 1 = 3
<h3>3 units²</h3>
Area of a Triangle = 1/2BH
B = 3
H = 2
1/2 × 3 × 2 = 3
<h3>3 units²</h3>
Area of a Triangle = 1/2BH
B = 2
H = 6
1/2 × 2 × 6 = 6
<h3>6 units²</h3><h3 /><h3>42 + 6 + 3 + 3 = 54</h3>
Answer:
Two Decimal Places Rule #1: If the last digit in 0.167 is less than 5, then remove the last digit. Two Decimal Places Rule #2: If the last digit in 0.167 is 5 or more and the second to the last digit in 0.167 is less than 9, then remove the last digit and add 1 to the second to the last digit.
