you can use long division to do this:-
a + 3 ) a^2 + 2a + 3
= a - 1 remainder 6 or you can write it as a - 1 + 6 / (a + 3)
Answer:
j : k : m = 4 : 12 : 15
Step-by-step explanation:
Given
j : k = 1 : 3 , then k = 3j
Given
k : m = 4 : 5
then expressing in fractional terms
= ( substitute k = 3j )
= ( cross- multiply )
4m = 15j ( divide both sides by 4 )
m = j , so
j : k : m = 1 : 3 : ( multiply each part by 4 to clear the fraction )
= 4 : 12 : 15
Answer:
$66.70
Step-by-step explanation:
58x.15= 8.70
8.70+58= 66.70
Answer:
450 feet at ground level
Step-by-step explanation:
The width of the bridge at ground level will be where the function intercepts the x-axis also known as the roots or zeros of the function. They are found using the zero product property to set each factor equal to 0.
This means (x-225) = 0 and (x + 225) = 0. So x = -225, 225.
This means the width is the absolute value of |-225| + 225 since distance cannot be negative. This makes it 450 feet.
To find the length of the missing side, subtract all of the known side from the perimeter.
14 + 19 + 25 = 58.
73 - 58 = 15.
The fourth side is 15 feet
I hope that helps!
