Answer:  Length of BC = 24 units.

Explanation:


Given that in triangle ABC, BC is the base, and angle B = angle C

SInce two angles are equal, ABC is isosceles with sides AB = AC

Given that AC = x+8 and AB = 2x-1

Since AB = AC we get these two are equal.  Use this t solve for x.

x+8 = 2x-1

x =9.

It is easy to find BC now.

BC =3x-3

Hence BC =3(9)-3 = 24

Length of BC= 24 units.

Answer:

24 unites

Step-by-step explanation:

Given that in triangle ABC, BC is the base, and angle B = angle C

SInce two angles are equal, ABC is isosceles with sides AB = AC

Given that AC = x+8 and AB = 2x-1

Since AB = AC we get these two are equal.  Use this t solve for x.

x+8 = 2x-1

x =9.

It is easy to find BC now.

BC =3x-3

Hence BC =3(9)-3 = 24

Length of BC= 24 units.

Which expression is equivalent to -18a^-2b^5/-12a^-4b^-6
crimeas [40]

Answer:

  c.  3a^2b^11/2

Step-by-step explanation:

The applicable rule of exponents is ...

  (a^b)/(a^c) = a^(b-c)

__

 \dfrac{-18a^{-2}b^5}{-12a^{-4}b^{-6}}=\dfrac{-18}{-12}a^{-2-(-4)}b^{5-(-6)}=\boxed{\dfrac{3a^2b^{11}}{2}}

Answer:

1. x =0; x = -7

2. x = -3; x = 10

3. x = -5; x = -4

Step-by-step explanation:

(1). 6x² + 42x = 0

6x (x + 7) = 0

6x = 0. OR. x + 7 = 0

x = 0/6. x = 0 - 7

x = 0. x = -7

x = 0

x = -7

(2). x² - 7x - 30 = 0

The factors here are (3, -10)

x² - 10x + 3x - 30 = 0

x ( x - 10) + 3 ( x - 10) = 0

(x + 3) ( x - 10) = 0

x + 3 = 0 OR. x - 10 = 0

x = 0-3. x = 0 + 10

x = -3. x = 10

x = -3

x = 10

(3). x² + 9x + 20 = 0

The factors are ( 4, 5)

x² + 4x + 5x + 20 = 0

x ( x + 4) + 5 ( x + 4) = 0

(x + 5) (x + 4) = 0

x + 5 = 0 . OR. x + 4 = 0

x = 0-5. x = 0 - 4

x = -5. x = -4

x = -5

x = -4
