s to be 256 square yards for the children to use it safely. The playground will be rectangular. The city will pay to have soft pavement made of recycled tires installed in the playground. In the first plan, one side 8 yards longer than the other side. Which equations model the possible dimensions of the playground? x( x + 8) = 256 ( x2) - 8 = 256 x2- 8 x - 256 = 0 ( x + 4)( x - 4) = 256 x( x - 8) = 256

Answer:

x(x+8) = 256

Step-by-step explanation:

hello

one side is x

the other one is 8 yards longer, so it is x + 8

so the surface is x(x+8) = 256

hope this helps

Answer:

x(x + 8) = 256

Step-by-step explanation:

The area of a rectangle can be calculated by doing length times width.

One side is 8 yards longer than the other. Let one side be represented by x. So, another side would be x + 8.

x * (x + 8) = 256

x(x + 8) = 256

x^2 + 8x = 256

Hope this helps!

wariber [46]

Answer:

No

Step-by-step explanation:

No because the ratio of the sides are different

9/6 = 1.5 whereas,

4/3 = 1.333

so the ratios are different and not the same so they are not similar.

A 12-foot ladder leans against the wall; the base of the ladder is 2 feet away from the wall.To the nearest tenth of a foot, how
ludmilkaskok [199]
<h3>The ladder will reach a height of 11.8 feet up the wall</h3>

<em><u>Solution:</u></em>

The ladder, wall and base of the ladder from wall forms a right angled triangle

Length of ladder forms the hypotenuse

Length of ladder = 12 foot

base of the ladder from wall = 2 feet

<em><u>To find: height of wall</u></em>

By pythagoras theorem.

c^2 = a^2+b^2

Where,

"c" is the Length of ladder

"a" is the base of the ladder from wall

"b" is the height of wall

Substituting the values,

12^2 = 2^2+b^2\\\\144 = 4 + b^2\\\\b^2 = 140\\\\b = \pm 11.832 \\\\Ignore\ negative\ value\\\\b \approx 11.8

Thus, the ladder will reach a height of 11.8 feet on wall

Wittaler [7]

Answer:

x ≈ 65.4 °

Step-by-step explanation:

cos x = \frac{adjacent}{hypotenuse}

Cos x = \frac{5}{12}

Cos x = 0.4167

x = Cos⁻¹ (0.1467)

x ≈ 65.4 °
