Answer:
29.4 cm^2
Step-by-step explanation:
We can use a proportion to find the height:
120 : 100 = x : 7
x = (120 *7)/100 = 8.4 cm
Area = (base * height)/2 = (7 * 8.4)/2 = 29.4 cm^2
The quotient to 1.44 and 0.4 equals to 3.6
F(x) = 5x - 4.....slope is 5
g(x) : (0,1)(2,5)
slope = (5 - 1) / (2 - 0) = 4/2 = 2 .....slope is 2
h(x) : (1,14)(4,15)
slope = (15 - 14) / (4 - 1) = 1/3..slope = 1/3
so the smallest slope would be : h(x) with a slope of 1/3
Easy, you just replace m with 2, and when a letter is placed next to a number then it means you multiply them, therefore
6*2-1=12-1 = 11
3/5 / 3/7
= 3/5 * 7/3
= 7/5 or 1 2/7
