Answer:

○ D. 29

Step-by-step explanation:

According to the Order of Operations [GEMS\BOMDAS\PEMDAS etc.], evaluate all expressions inside grouping symbols, take care of the exponents, indices, roots, etcetera, evaluate Division & Multiplication from left to right, then evaluate Subtraction & Addition from right to left [or left to right, as long as you know what you are doing correctly]:

$(5 + 1)^{2} - (12 + {3}^{2}) \div 3 = {6}^{2} - (12 + 9) \div 3 = \\ \\ 36 - 21 \div 3 = 36 - 7 = 29$

I am joyous to assist you anytime.

Ms.hernandez has $100 to spend on parking and admission to the zoo. The parking will cost $7, and admission tickets will cost $1

Mice21 [21]

The answer is Ms Hernandez can bring up to 6 people to the zoo.

x - the number of people that she can bring to the zoo
The parking will cost $7: a = 7
Admission tickets will cost $15.50 per person: b = 15.50x
She can spend on parking and admission tickets $100:
a + b ≤ 100

a = 7
b = 15.50x

7 + 15.50x ≤ 100
15.50x ≤ 100 - 7
15.50x ≤ 93
x ≤ 93 / 15.50
x ≤ 6

The cost of fabric (y) is directly proportional to he length is yards (x). If 5 yards of fabric cost $14, which equation models

marta [7]

Answer:

5x = 14

Step-by-step explanation:

If 5 yards of fabric is $14 you need an equation that would solve how much 1 yard of fabric costs. You can say 5x = 14 or x = 2.8 which means that one yard of fabric (1x or just x) is $2.80.

Solve the equation after making an appropriate substitution. X^6-98x^3=3375

Leni [432]

Rearrange $x^6-98x^3=3375$ to give

$x^6-98x^3-3375=0$

Let $x^3$ be a variable 'p' and so we can write $x^6$ as $x^6=(x^3)(x^3)=(p)(p)= p^2$

Rewrite the equation in terms of 'p'

$p^2-98p-3375 = 0$

where $a=1, b=-98, c=-3375$

using the quadratic formula $\frac{-b+ \sqrt{b^2-4ac} }{2a}$ and subsitute the value of $a, b, c$

$p_1= \frac{-(-98)+ \sqrt{(-98)^2-4(1)(-3375)} }{2} =125$

$p_2= \frac{-(-98)- \sqrt{(-98)^2-4(1)(-3375)} }{2} =-27$

There are two value of p; 125 and -27

Now we find the value of x

Earlier we substitute $x^3$ for $p$ and $x^6$ for $p^2$

When $p=125$ , $x= \sqrt[3]{125}=5$
When $p = -27, x= \sqrt[3]{-27}=-3$

So the final answer is the two values of x;

x = 5 OR x = -3
