Rosy has 16 pencils and 24 erasers. She is putting together packets that will havean equal number of pencils and erasers in each

N76 [4]

$16 = 2^4$

$24 = 2^3 \times 3$

$\text{HCF =}2^3 = 8$

Maximum number of packets = 8

16 ÷ 8 = 2
There are 2 pencils in each packet.

24÷8 = 3
There are 3 erasers in each bag.

Rosy can have a maximum of 8 packets. Each packet has 2 pencils and 3 erasers.

Please help question in the picture

Natalka [10]

Answer: use the Pythagorean theorem a2+b2=c2 substitute the numbers in

7 squared + 3 squared = c squared so 7x7=49 and 3x3=9 add 49 and 9 which equals square root of 58 since that is not a perfect square you take square root of 58 and you simplify and that gives you 7.62

What is the fifth term in the binomial expansion of (x + 5)8?

AlekseyPX

$(a+b)^n\\
\displaystyle
T_r=\binom{n}{r-1}a^{n-r+1}b^{r-1}\\\\
T_5=\binom{8}{5-1}x^{8-5+1}\cdot5^{5-1}\\
T_5=\binom{8}{4}x^4\cdot5^4\\
T_5=\dfrac{8!}{4!4!}\cdot x^4 \cdot5^4\\
T_5=\dfrac{5\cdot6\cdot7\cdot8}{2\cdot3\cdot4}\cdot x^4\cdot5^4\\
T_6=2\cdot7\cdot x^4\cdot5^5\\
T_6=43750x^4

Simplify using PEMDAS<br>(3X + 2x)(3+4)

katrin [286]

Answer:

$5x*7$

Step-by-step explanation:

We know that PEMDAS is a shortened acronym for the order in which we do operations in an expression, which is as following in the correct order:

Parenthesis, Exponents, Multiplication, Division, Addition, Subtraction.

Now your question asks you to solve the expression using PEMDAS, however that is what we would do regardless as <em>in algebra </em>PEMDAS is always in effect.

Lets break it down! $(3x+2x)*(3+4)$

Simple enough! We just do the respective operations inside the parenthesis first (as per pemdas), which after completion yields us

$5x*7$

Since x is undefined and the expression is completely simplified, there is nothing more we can do.
