Archy [21]3 years ago
8 0

The length of the diagonal should be 18 if I am not wrong!

Step-by-step explanation:

a2+ b2=c2

so 10x10+15x15=the diagonal

100+225=325

325 squared = 18

Answer:

  (x, y) = (-3, -13) or (-8, -23)

Step-by-step explanation:

The values for y can be equated and the resulting quadratic solved by factoring.

  2x -7 = x^2 +13x +17

  0 = x^2 +11x +24 . . . . . . subtract 2x-7

  0 = (x +8)(x +3) . . . . . . . .factor*

The values of x that make these factors zero are x=-8 and x=-3. The corresponding values of y are ...

  y = 2(-8) -7 = -23

  y = 2(-3) -7 = -13

The solutions are ...

  (x, y) = (-8, -23) and (-3, -13)

_____

* The constants in the binomial factors are factors of 24 that total 11. You know that ...

  24 = 1×24 = 2×12 = 3×8 = 4×6

The sums of these factors are 25, 14, 11, 10. The factors 3 and 8 are the constants in the binomial factors of the quadratic.

"24" is the constant in the quadratic. "11" is the coefficient of the x term.

What is the length of BC? If your answer is not an integer, leave it in simplest radical form?
nexus9112 [7]
ANSWER

|BC|=12\sqrt{2}\: ft

EXPLANATION

The given right triangle is an isosceles triangle because

m \: < \: B = 45 \degree = m \: < \: C
This implies that,

|AB|=12ft=|AC|

From the Pythagoras Theorem,

|BC|^2=|AB|^2+|AC|^2

|BC|^2= {12}^{2} + {12}^{2}

|BC|^2=2 \times {12}^{2}

|BC| = \sqrt{ {12}^{2} \times 2 }

|BC|=12\sqrt{2}\: ft

BRIANILEST!!!!Which lines are parallel? Check all that apply.
spin [16.1K]

Answer:

b║f

c║e

Step-by-step explanation:

Given a diagram,

Lines b, c, d, e, f and a transversal line 'a'.

Here line 'b' makes an angle with line 'a' is 89.5° and line 'f' makes an angle with line 'a' is also 89.5° (180°-90.5° = 89.5°)

Since corresponding angles are same.

So, line 'b' is parallel to line 'f'.

And line 'c' makes an angle with line 'a' is 91.5° and line 'e' makes an angle with line 'a' is also 91.5° (180°-88.5° = 91.5°)

Since corresponding angles are same.

So, line 'c' is parallel to line 'e'.

Therefore,

b║f

c║e

That's the final answer.
