okay so you should know that the formula for a triangle is:
A=1/2×b×h
where b is breadth and h is height
A is area
so they already gave the area which is 16.2 and they already gave a side ( doesn't matter if it's b or h in this question)
so we put these into the equation of the area of a triangle
A=1/2×b×h
16.2=1/2 × 6 × h
then you will solve algebraically to get 5.4cm which is you answer
to check if correct you can always put in all numbers in equation and you should get 16.2cm
In this case it's correct ✌
Answer:46
Step-by-step explanation:
The slope is 0.10
The y-intercept is 30
The slope, which is 0.10, represents how much is changed per mile driven.
The y-intercept, which is 30, represents the base price to rent the car.
c = 0.10m + 30 represents the situation.
120 * 45 % = 120 *0,45 = 54 £
120 -54 = 66 £
7 = 2n - 2
n= a number so twice a number is 2n and 7 is 2 less than twice this number.
