Answer:
Step-by-step explanation:
What this means is when you start with P(x) you get 10^2 + 10x - 3 on the right
p(-4) has the meaning that when you see an x on the right hand side, you put in -4 for that x. Do this procedure for every x on the right.
p(-4) = 10(-4)^2 + 10(-4) - 3
p(-4) = 10*16 + (-40) - 3
p(-4) = 160 - 40 - 3
p(-4) = 120 - 3
p(-4) = 117
Answer:
69 Pieces of candy
Step-by-step explanation
So you get 3 pieces of candy at every house. And you do that 23 more times. We can right that out as 23*3. Which is 69.
perimeter of triangle: P = l+w+h
9+12+10= 31in.
area of triangle: A=b×h÷2
21 + 21 = 42in^2
Answer:
I assume you are looking for the length and width of the rectangle?
W = 6 meters L = 14 meters
Step-by-step explanation:
P= 2(l + w)
We are given that the length is 2 meters more than double the width.
Let width = x
Let length = 2x + 2
Calculate P based on these.
2 [2x + 2 + x]
2 [3x + 2]
6x + 4 = P
Substitue 40 for P
6x + 4 = 40
6x = 36
x = 6
Substitute 6 in for x in the length and width formulas.
W = 6
L = 14
Check
6 + 14 = 20
And 20 times 2 = 40 meters.
