Answer:

-20

Step-by-step explanation:

a2 + ( b-c)

rewrite the equation

2 * a + ( b - c )

a = -8

b = 17

c = 21

substitute in the given values

(-8) 2 + ( (17) - (21) )

simplify and solve

-16 + ( 17-21)

= -16 +  (-4)

= -16 -4

=-20

The question is incomplete. Here is the complete question:

Mr.yueng graded his students math quizzes students came up with four different answers when solving the equation x3=22. Which answers is correct.

(A) \frac{22}{3}

(B) \sqrt[3]{22}

(C) \pm \sqrt[3]{22}

(D) \sqrt{22}

Answer:

(B) \sqrt[3]{22}

Step-by-step explanation:

Given:

The equation to solve is given as:

x^3=22

Here, the left hand side of the equation has a variable 'x' in exponent form. So, in order to solve for 'x', we have to eliminate the exponent.

For removing the exponent, we have to take cubic root on both the sides. As we know that,

\sqrt[n]{x^n} =x

So, taking cubic root on both the sides, we get

\sqrt[3]{x^3}=\sqrt[3]{22}\\\\x=\sqrt[3]{22}

Therefore, the second student has written the correct answer and hence the correct option is (B).

Step-by-step explanation:

Area = 42x + 56

length * width = 14* 3x + 14*4

14 * width = 14*(3x+4)

width=\frac{14*(3x+4)}{14}\\\\width=3x+4

Write an equation to find the amount of interest $450,000 earns in 1 year at a simple interest rate of 3.5%.
telo118 [61]

Answer:

The required equation for the amount of Simple Internet = \frac{450,000 \times 1 \times 3.5}{100}

Step-by-step explanation:

Here , Principal amount = $450,000

Time  = 1 year

Rate of Interest = 3.5%

Now,SIMPLE INTEREST  = \frac{P \times R \times T}{100}

So, here SI  = \frac{450,000 \times 1 \times 3.5}{100}

Hence, the required equation for the amount of Simple Internet = \frac{450,000 \times 1 \times 3.5}{100}
