Mathematics
1 answer:
MAXImum [283]2 years ago
5 0

Answer:

BC = 10

Step-by-step explanation:

Since this is an isosceles triangle

AC = BC

3x-5 = 2x

Subtract 3x from each side

3x-5-3x = 2x-3x

-5 = -x

Multiply each side by -1

5 =x

BC = 2x

     =2 *5

BC =10

Can someone help me really please
JulsSmile [24]

Answer:

26

Step-by-step explanation:

Let x represent the missing number

8\frac{11}{15} = 7\frac{x}{15}

Convert both fractions to improper fractions

\frac{131}{15} = \frac{105 + x}{15}

Cross multiply

15(105 + x) = 15(131)

1,575 + 15x = 1,965

Subtract both sides by 1,575

15x = 1,965 - 1,575

15x = 390

Divide both sides by 15

x = \frac{390}{15}

x = 26

Use the Rational Zeros Theorem to write a list of all potential rational zeros f(x) = 14x^3 + 56x^2 + 2x - 7
Crank
The factors of 7are -1 and 7 or 1 and -7, the factors of 14 are 1, 2, 7, and 14, or -1,  -2, -7,-14. so the list of potential zeros are: 1/1, 1/2, 1/7, 1/14, 7/1,7/2, 7/7, 7/14, which can be simplified into 1, 1/2,1/7, 1/14, 7, 7/2
add the negative ones: -1, -1/2,-1/7, -1/14, -7, -7/2
I believe there are a total of 12 potential zeros
