Answer:
As this is triangular height and floor length we multiply and divide by 2 (representing halving the square)
= 3.5 x 6= 19 19/2 = 9.5ft
To thereafter measure the angle we can see 9.5/3.5 =2.711
so we have 90, 27 and 63 degree.
As this is decimal we round up to 30 degree. and round down to 60 degree.
Step-by-step explanation:
Answer: 12x² - 5x - 2
Concept:
When doing questions that need to expand algebraic expressions, using the FOIL method will ease the process:
- <u>First </u>means that we multiply the terms which occur in the first position of each binomial.
- <u>Outer</u> means that we multiply the terms which are located in both ends (outermost) of the two binomials when written side-by-side.
- <u>Inner </u>means that we multiply the middle two terms of the binomials when written side-by-side.
- <u>Last </u>means that we multiply the terms which occur in the last position of each binomial.
Solve:
<u>Given expression</u>
(3x - 2) (4x + 1)
<u>Expand parentheses and apply the FOIL method</u>
First: 3x · 4x = 12x²
Outer: 3x · 1 = 3x
Inner: (-2) · 4x = -8x
Last: (-2) · 1 = -2
12x² + 3x - 8x - 2
<u>Combine like terms</u>
12x² + (3x - 8x) - 2
Hope this helps!! :)
Please let me know if you have any questions
Assuming the equation reads:
Add 16 to both sides:
Multiply both sides by 5 to get rid of the denominator and to get x by itself:
The value of x will be
70.

The 2 marked angles add up to 180 if m and n are parallel.
I cant solve for x because the image is very unclear.
