Answer:
3cm
Step-by-step explanation:
cb is the same length bisector ac, so the answer is <u>3 cm</u>
Ok, so
Length = L
Width = L + 7
Since area = length x width, then
30 = L × (L + 7)
Remember that L + 7 Is width so...
L + 7 = 30/L
So the expression for the width in terms of length would be...
w = 30/L - 7
Since there was five boxes of crayons and there was 3 crayons in each one, the would be 15 in total. (crayons) And there was three people, 15/3=5 crayons per person.
Equation: 3x=15
x stands for the amount of crayons each person gets.
