Answer:
(x+5/2)^2 = 0
Step-by-step explanation:
4 x^{2} +20x +25 =0
Divide by 4
4/4 x^{2} +20/4x +25/4 =0
x^2 +5x +25/4 =0
Subtract 25/4 from each side
x^2 +5x +25/4 -25/4 =-25/4
x^2 +5x =-25/4
Take the coefficent of x
5
Divide by 2
5/2
Square it
25/4
Add it to each side
x^2 +5x +25/4 =-25/4+25/4
(x+5/2)^2 = 0
Take the square root of each side
x+5/2 = 0
x = -5/2
Answer:
C

Hey There!
So if you didn't know in an isosceles trapezoid the non parallel sides are congruent
So given the base lengths and the perimeter we subtract the given length from the perimeter and divide that by 2
40-10=40
30-14=16
16/2=8
so the lengths of the non parallel sides would be 8 cm and 8 cm
The distance traveled by first car is 50t + 100.
The distance traveled by second car is 70t.
The distance between the two cars after time, t is d = 100 - 20t.
The ratio of the distance traveled by the cars is (70t) / (50t + 100).
<h3>
Distance traveled by each vehicle is calculated as follows;</h3>
The distance traveled by each vehicle at the given time is calculated as follows;
<h3>Distance traveled by first car</h3>
D₁ = speed x time
D₁ = 50(t + 2)
D₁ = 50t + 100
<h3>Distance traveled by the second car</h3>
D₂ = 70t
<h3>Distance between the two cars after time, t</h3>
d = D₁ - D₂
d = (50t + 100) - 70t
d = 100 - 20t
<h3>Ratio of the distance traveled by the cars</h3>
D₂/D₁ = (70t) / (50t + 100)

Area of triangle = 0.5 base height
24 = 0.5 x 6 height
height = 8 inches
Answer:
there are three different types of answers to this and all of them have to do with the perspective of pi
1) if you don't want to see the decimals and you want to leave pi alone your answer would be this
3pi
2) if you want to solve for pi it would be
9.43 respectively
3) if you want pi to just be narrowed down to 3 digits 3.14 your answer would be
9.42
Step-by-step explanation:
formula
C=2*pi*R
plug in
2*pi*1.5
