3b+4b^2-a^3;a=3 and b=-5

Alik [6]

Equation: 3b+4b^2-a^3
Given: a=3 & b=-5

Plug 3 in for (a) and -5 in for (b):
3(-5)+4(-5)^2-(3)^3

Now follow PEMDAS:
3(-5) + 4(-5)^2 - (3)^3
-15 + 4(-5)^2 - (3)^3
-15 + 100 - (3)^3
-15 + 100 - 27
85 - 27
58
the asnwer is 58.

Solve step by step. 7x+4(4x-14)=59

ziro4ka [17]

Answer:

$x = 5$

Step-by-step explanation:

$7x+16x-56=59$

$23x -56 = 5 9$

$2 3 x - 5 6 + 5 6 = 5 9 + 5 6$

$23x=115$

$\frac{23x}{23} = \frac{115}{23}$

$x = 5$

An ice cream store sells 28 flavors of ice cream. Determine the number of 4 dip sundaes.

katrin [286]

Answer:

$20,475\ ways$

Step-by-step explanation:

we know that

Combinations are a way to calculate the total outcomes of an event where order of the outcomes does not matter.

To calculate combinations, we will use the formula

$C(n,r)=\frac{n!}{r!(n-r)!}$

where

n represents the total number of items

r represents the number of items being chosen at a time.

In this problem

$n=28\\r=4$

substitute

$C(28,4)=\frac{28!}{4!(28-4)!}\\\\C(28,4)=\frac{28!}{4!(24)!}$

simplify

$C(28,4)=\frac{(28)(27)(26)(25)(24!)}{4!(24)!}$

$C(28,4)=\frac{(28)(27)(26)(25)}{(4)(3)(2)(1)}$

$C(28,4)=20,475\ ways$
