We can solve for the equivalent expression of the given expression:
√(x+6) + √x = 8
First, we need to square both sides such as shown below:
((√x+6) + (√x) =8)²
(x+6) + x = 64
Perform transposition and combine similar terms
x + 6 + x =64
2x = 64 -6
x = 29
Hello!
Ok so we have y= 7/3x + 5 and initial condition of x=-3 so we just plug -3 in for x and chug along at this point! :)
y=(7/3)*(-3/1)+5= -7+5 = -2
Hope this helps! Any questions please just ask! Thank you!!
Answer:
Step-by-step explanation: Just so you know we need to see the whole problem and l am actually already learned this im just finished with the Ratios
25 -3x = -8
subtract 25 from each side
-3x = -33
divide by -3
x = 11
check
25 -3x = -8
25 -3(11) = -8
25 - 33 = -8
-8 = -8
From the measure of 40°, you can write
tan(40°) = 100/x, where x is the base from the building to the tower
⇒x=100/tan(40°) = 119,18 m
2) From the measure of 30°, you can write
tan(30°) = y / 119,18, where y is the height from the roof of Jill's building to the top of the tower.
Then, y = tan(30°) * 119,18 = 68,81 m
3) The height of Jill's building is 100 - 68,81 = 31,19 m
