4708 - 308 = 4400. You subtract it because the current was 308 more so the last time has to be 308 less.
Answer:
The student answers 15 answers correctly.
Answer:
A) L = 2*W
B) 2L + 2W = 42
We'll put Equation A) into B)
2*2W + 2W = 42
4W + 2W = 42
6W = 42 cm
Width = 7 cm
Length = 14 cm
Step-by-step explanation:
Since it is shown that 2 of the sides of the triangle are congruent, we can assume that they have the same angle measures.
so to solve for the missing angle you can set up an equation equal to 180 since all triangles add up to 180 degrees.
21 + 21 + x = 180
42 + x = 180
x = 138
the value of the missing angle should be 138 degrees
hope this helped
For every x you see in the f function you will replace with the h function
