Answer:
±35
Step-by-step explanation:
sqrt(49*25)=sqrt(49)*sqrt(25)=±7*±5=±35
The volume of this right rectangular prism is 263.52 and it is to the nearest hundredths as a decimal, hope it helps!
Firstly mines 2x for 2 side
And combine 1 for 2 side
Result 6x^2+17x+5
So
(3x+1)(2x+5)=0
X=-1/3 or x=-5/2
Answer:
24; 118; 102
Step-by-step explanation:
Starting from A: there are two ways. One, is a theorem that says "the amplitude of the external angle of a triangle is equal to the sum of the amplitudes of the two angles not sharing the vertex". Which translates to the equation
which has solution
.
Problem B is a red herring: x and 118° are corresponding angles related to the two parallel lines with a transversal, and they have the same amplitude, thus 
Finally, letter C : you know the sum of the internal angles of a triangle is 180°. It means that
or, with simple calculations (subtract 41 and 37 from both sides)
