Answer:
Step-by-step explanation:
The following is the logarithm quotient rule:
Plugging in the values we have above gives us the following:
Answer:
B) 81°
Step-by-step explanation:
∡1 ≅ ∡5 because they are corresponding angles
∡5 ≅ ∡7 because they are vertical angles
therefore, ∡1 ≅ ∡7
since the angles are equal we can create the following equation:
3x + 18 = 2x + 39
x + 18 = 39
x = 21
∡7 = 2(21) + 39
∡7 = 42 + 39
∡7 = 81
Since you know the area and the width, you can divide the area by the width to find the length. This gives you a length of 110 yards. To find the perimeter of the soccer field, you would add all the side lengths together. Since the width is 70, you would add 70 + 70, along with the length, 110 + 110. This gives you a perimeter of 360.
The equation seems to be invalid. Is that the equation from your homework? Both sides of the equation dont seem to be equal to each other. This equation would have no solution, instead of one or infinite solutions.
Answer:
x=4
Step-by-step explanation:
multiply both sides by 5: 2x-8= -5x+20
move the -5x over: 7x-8= 20
move the -8 over: 7x= 28
divide both sides by seven: x= 4
