Answer:
<u>If P is 30 units and l is 10 units, w is 5 units</u>
Step-by-step explanation:
1. Let's check the information given to resolve the question:
P = 2l + 2w
If P is 30 units and l is 10 units, w is units
2. Replacing with the values:
P = 2l + 2w
30 = 2 (10) + 2w
30 = 20 + 2w
-2w = 20 -30 (Subtracting 2w and - 30 to both sides)
-2w = - 10
2w = 10 (Multiplying by - 1 at both sides)
<u>w = 5 (Dividing by 2 at both sides)</u>
<u>If P is 30 units and l is 10 units, w is 5 units</u>

Answer:
4(x - 2)^2 + 3x – 2 + 1 = 0
Step-by-step explanation:
The equation that has a highest x-power (degree) of 2 is quadratic.
The degrees of the answer choices are ...
So, only the first answer choice is a quadratic.
Answer:
x intercept = -7/2
y intercept = 21/5
Step-by-step explanation:
-6x +5y = 21
To find the x intercept, set y=0 and solve for x
-6x +5(0) =21
-6x =21
Divide each side by -6
-6x/-6 = 21/-6
x = -21/6 = -7/2
To find the y intercept, set x=0 and solve for y
-6(0) +5y = 21
5y =21
Divide each side by 5
5y/5 =21/5
y = 21/5

Step-by-step explanation:
Probability of choosing pink balloon is 
.
Step-by-step explanation:
Given,
Number of green balloons = 5
Number of yellow balloons = 3
Number of red balloons = 4
Number of pink balloons = 8
Total number of balloons = 5+3+4+8 = 20
To find the probability of pink balloon.
Formula
Probability of an even = number of outcomes ÷ total number of outcomes
So,
Probability of choosing pink balloon = 
=
