27) 3 (-5) (-7)
When there is no math symbol between numbers it is multiplication.
Multiply from left to right:
3 * -5 = -15
-15 * -7 = 105
28) -2 * 2 (-3) *2 =
-2 *2 = -4
-4 * -3 = 12
12*2 = 24
31) A negative divided by a negative is positive:
-128 / -4 = 32
32 -36 / 2 / 24 /4
Divide the top and bottom first then divide those:
-36 / 2 = -18
24 / 4 = 6
-18 / 6 = -3
For the first question, all you have to do is substitute the values. for example g(x)=-5x+2 becomes g(-1)=-5(-1)+2
Answer:
76,800
Step-by-step explanation:
Given the following :
Length = 20 kilometers
Width = 12 kilometers
Population density = 320 people per sq km
Population =?
Recall:
Area of rectangle = Length × width
Therefore,
Area of Rectangleville = 20 km × 12 km = 240km^2
Population is related to population density and Area by the formula ;
Population density = population ÷ Area
Therefore,
Population = population density × Area
Population = 320 × 240 = 76,800
Therefore, the population of Rectangleville is 76,800 people
96 → B
substitute w = 12 into the equation D = 3w + 60
D = (3 × 12 ) + 60 = 36 + 60 = 96
