I'm not so good but I think thatmeans r is a different number and its half of 14 so figure out an equation
The unit rate is $1.97 per lightbulb. Multiply $1.97 by 7 to get 13.79
Use the equation
A= 2(wl +hl +hw)
Where
w is width
h is height
l is length
Answer:
x = 9.9 in.
Step-by-step explanation:
area of triangle = base * height /2
49 = x*x /2
49*2 = x^2
98 = x^2
= x
= x
9.9 = x
