Answer:
15y^2-45
Step-by-step explanation:
5y^2+10y^2-45 = 15y^2-45
Answer: 70 meters
Step-by-step explanation:
Hi, since the situation forms a right triangle and a rectangle, we have to apply the Pythagorean Theorem (for the triangle)
c^2 = a^2 + b^2
Where c is the hypotenuse of the triangle (the longest side) and a and b are the other sides.
Replacing with the values given:
65^2 = 16^2 + x^2
4,225 = 256 + x^2
4,225-256 = x^2
3,969=x^2
√3,969 =x
63=x
We have calculated the missing side of the triangle, now we have to add the height of the rectangle:
63 +7 =70 meters
Feel free to ask for more if needed or if you did not understand something.
Answer:
it ain't
Step-by-step explanation:
x = -8
y = 2
-(-8) - 2(6) > 12
8 - 12 > 12
-4 > 12
This is incorrect
The length of UV and RS is 72.2in and 114 in respectively
<h3>Similarity theorem of triangles</h3>
From the given truss. you can see that:
VW = UR = RS = 57in
Get the length of RS
- RS = UR + US
- RS = 57 + 57
- RS = 114 inches
To get the length of UV, we will use the expression
SU/UV = SR/RT
57/UV = 114/90
UV = 72.2in
Hence the length of UV and RS is 72.2in and 114 in respectively
