Answer:
Step-by-step explanation:
We know that a triangle equals to 180 degrees.
(2x+24)+(4x+43)+(x^2+1)=180
the awnser to this is x=8.
You plug in 8 into x
Angle 1: 2(8+24) --> 40
Angle 2: 4(8+43) -->75
Angle 3: (8^2+1) -->65
Check your work: add values together 40+75+65=180

Answer:
13
Step-by-step explanation:
Answer:
a. The function is increasing when and decreasing when .
b. The function is greater than zero when and
c. The function is less than zero when
Step-by-step explanation:
a. The function is increasing when it's instantaneous slope ( the slope of the line tangent to the graph ) is positive, and it is decreasing when the instantaneous slope is negative. We see from the graph of that for the instantaneous slope is positive, and for the slope is negative.
b. From the graph we see that the function is greater the zero (has positive values ) when and.
c. The graph of the function is less than zero ( is negative) when
1.) Angles between two sides is 90° in square , not necessarily in rhombus.
2.) Diagonals in a square are of equal length , not so in a rhombus .
