I WILL GIVE MEDAL AND BECOME FAN

A community group is planning the expansion of a square flower garden in a city park. If each side of the original garden is increased by 9 meters, the new total area of the garden will be 169 square meters. Find the length of each side of the original garden.

A. 9 m
B. 13 m
C. 2 m
D. 4 m

Please tell me the answer and how you got it
Thanks!

Answer 1

169 squared is 13 and the old garden was increased by 9 so 13-9=4m

Answer 2

Ohhhhh I'm a dummy >.< Thanks so much for helping! Can you help me with a little bit more please? :)

Answer 3

Sure

Answer 4

Solve the equation using square roots.

5x^2-30=0

A. x=6,-6
B. x=Square Root of 6, Square Root of -6
C. x=3, -3
D. No solutions

Answer 5

Simplifying
5x2 + -30 = 0

Reorder the terms:
-30 + 5x2 = 0

Solving
-30 + 5x2 = 0

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '30' to each side of the equation.
-30 + 30 + 5x2 = 0 + 30

Combine like terms: -30 + 30 = 0
0 + 5x2 = 0 + 30
5x2 = 0 + 30

Combine like terms: 0 + 30 = 30
5x2 = 30

Divide each side by '5'.
x2 = 6

Simplifying
x2 = 6

Take the square root of each side:
x = {-2.449489743, 2.449489743}

Answer 6

So it's B? :)

Answer 7

Answer 10

Solve the equation by completing the square. Round to the nearest tenth.

x^2+8x=10

A. 1.1, 9.1
B. 1.1, -9.1
C. -1.1, 9.1
-1.1, -9.1

Answer 11

I'm sorry... I can't help with that one.
I keep getting x1 equals the square root of 26-4 and x2 equals negative the square root of 26-4.
