Answer:
2/3 , -1/4
Step-by-step explanation:
(3x - 2)(4x + 1) = 0
Either 3x - 2 = 0 or 4x + 1 = 0
or, x = 2/3 or x = -1/4
Answer:
28 feet
Step-by-step explanation: I think it’s 28 feet because in the first part it says “A 3 foot tall tree casts a 12 foot shadow“ and since 3x4=12 the 7 foot man would cast a 28 foot shadow because 7x4=28

Answer:
86.53
Step-by-step explanation:
Area of Triangle Formula: A = 1/2bh
Pythagorean Theorem: a² + b² = c²
Step 1: Draw altitude and label numbers
If we draw a line down the middle, we can see that we get a perpendicular bisector and that we get 2 right triangles with a hypotenuse of 29 and a leg of 3. We need to find <em>h</em> using Pythagorean Theorem in order to use area formula:
3² + b² = 29²
b² = 29² - 3²
b = √832 = h
Step 2: Plug in known variables into area formula:
A = 1/2(√832)(6)
A = 3√832
A = 86.5332
The correct option is B i.e. .
<u>Step-by-step explanation:</u>
We have the following expression , . As we see the options there aren't in iota or in complex number hence, the correct expression to evaluate must be , . Let's evaluate the expression to simplify:
