Answer:
28
Step-by-step explanation:
Triangle on the right id dilated with scale factor 2 ( the sides of the other triangle are double (17-34 8-16 15-30
Dilations preserve angle measurement
C=90 + B=62=152
All triangles sum up to 180
180-152=28
Angle A=28
Angle A is corresponding with angle D
So angle D is also 28

Answer: Negative</h3>
======================================================
Explanation:
3/7 = 0.42857 approximately
Pick a number between that value and 5, not including either endpoint. Let's say we pick x = 2
Plug x = 2 into the f(x) function
f(x) = (x - 5)(2x + 7)(7x-3)
f(2) = (2 - 5)(2*2 + 7)(7*2-3)
f(2) = (2 - 5)(4 + 7)(14-3)
f(2) = (-3)(11)(11)
f(2) = -363
The actual result doesn't matter. All we're after is whether the result is positive or negative. We see the result is negative. This means f(x) is negative when 3/7 < x < 5. The f(x) curve is below the x axis on this interval.
