One along the X-axis and one along the y- axis
Answer:
A
Step-by-step explanation:
The distributive property: a(b + c) = ab + ac
(x - 3)(4x + 2) = (x)(4x + 2) + (-3)(4x + 2)
= (x)(4x) + (x)(2) + (-3)(4x) + (-3)(2) = 4x² + 2x - 12x - 6
<h3>= 4x² - 10x - 6</h3>
Answer:
x = 22
y = 35
Step-by-step explanation:
Because its an isosceles triangle, you know the base angles are equal so:
![3x - 11 = 2x + 11](https://tex.z-dn.net/?f=3x%20-%2011%20%3D%202x%20%2B%2011)
Solving:
subtract 2x from both sides
![x-11=11](https://tex.z-dn.net/?f=x-11%3D11)
add 11 to both sides
![x = 22](https://tex.z-dn.net/?f=x%20%3D%2022)
Next, find the angle measures of the two base angles:
![3*22-11\\66-11\\55](https://tex.z-dn.net/?f=3%2A22-11%5C%5C66-11%5C%5C55)
To find y, you know that the interior angles of the whole triangle add up to 180, so you have
![55 + 55 + 2y = 180](https://tex.z-dn.net/?f=55%20%2B%2055%20%2B%202y%20%3D%20180)
solving,
![110 + 2y = 180](https://tex.z-dn.net/?f=110%20%2B%202y%20%3D%20180)
subtract 110 from both sides
![2y = 70](https://tex.z-dn.net/?f=2y%20%3D%2070)
divide both sides by 2
![y = 35](https://tex.z-dn.net/?f=y%20%3D%2035)
Answer:
the answer would be 13.75 feet
Step-by-step explanation:
The computation of the tall is the building as follows:
Given that
Base is 6 foot
And, the hypotheses is 15 feet
Here we use the Pythagoras theorem
= √15^2 - √6^2
= √225 - √36
= √189
= 13.75 feet
Hence the answer would be 13.75 feet
