Step-by-step explanation:
Rewrite the expression using only positive exponents. Then, evaluate the expression. 3^{-2}
Answer:
x=−7/8
Step-by-step explanation:
Answer:
p = 3
q = -6
Step-by-step explanation:
Work backwards from the roots:
x = 
3x = 2
3x - 2 = 0
Other root:
x = -3
x + 3 = 0
Multiply them together:
(3x - 2)(x + 3) = 0
3x² - 9x + 2x - 6 = 0
3x² - 7x - 6 = 0
p = 3
q = -6
These are the steps:
1. Find area of the two triangles.
2. Find area of the rectangle.
3. Add them up.
<u>Step 1: Find area of the two triangles:</u>
Formula : Area of triangle = 1/2 x base x height
Both triangles are identical.
Height = 5m
Base = 6 + 6 + 12 = 24
Area = 1/2 x 24 x 5 = 60 m²
<u>Step 2: Find the area of the rectangle:</u>
Formula : Area = Length x Width
Area = 12 x 7 = 84 m²
<u>Step 3: Find the total area:</u>
60 + 84 = 144 m²
Answer: 144 m²
