Zach created a model of his
dad's truck using a scale of
1 inch : 3 feet. If the width
of the model truck is 2.4 inches,
then the width of Zach's dad's
truck is
ft.

7.2 ft

Step-by-step explanation:

Since Zach used a scale of 1:3, we just need to multiply the width of the model truck by 3 ft in order to figure out the width of the actual truck

13

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13

answer:   x = 3 + √11     and     x = 3 - √11

step-by-step explanation:

x² - 6x + 9 = 11

(x - 3)² = 11

x - 3 = ±√11

    x = 3 ± √11

x = 3 + √11     and     x = 3 - √11
