√(-15+15)² + (-3-20)²
=√0²+(-23)²
=√529
=23 units

Your basketball team scored 4 fewer than twice as many points, x, as the other team. a. Write an expression for the number of po

velikii [3]

Answer:

A) p = 2x - 4 for the expression. B) Your team scored 44 points.

Step-by-step explanation:

Let P represent the points your team made.

Since the question says "Your basketball team scored 4 fewer than twice as many points as the other team." this is how I came up with the expression.

p = 2x - 4 ( our points = 2 times more then the other teams points minus 4.

Using this expression and the given information that the other team made 24 points, I solved B.

44 = 2(24) - 4.

Could someone help? Thank you

Answer:

See Below

Step-by-step explanation:

Thankfully, all the parts you need are given.

First, find the surface of one triangle

A = 1/2bh

A = 1/2(15)(9)

A = 1/2(135)

A = 67.5

Multiply by 4 to get the sum of all the sides.

67.5(4) = 270

Now find the surface area of one square

A = bh

A = (15)(15)

A = 225

multiply by 5 to get all 5 sides

225(5) = 1125

Add sums together

1125 + 270 = 1395

What is the value of x? A. 2 Units B. 3 Units C. 5 Units D. 8 Units

Fudgin [204]

You need the formula for geometric mean for right triangles as it applies to the altitude. For us, that formula will be $\frac{BD}{AD}=\frac{CD}{BD}$ where BD is your altitude. The formula then, filled in accordingly, would be $\frac{10}{x}=\frac{4x}{10}$ . We cross multiply to get that $4x^2=100$ . Divide both sides by 4 to get $x^2=25$ , so x = 5. Choice C is the one you want.
