If you want to factor, then you need to find two numbers that multiply to 4 and add to -5. Those two numbers are -4 and -1

-4 times -1 = 4

-4 plus -1 = -5

This means x^2-5x+4 factors to (x-4)(x-1). The order of the factors does not matter, as we can multiply in any order, so it is equivalent to (x-1)(x-4)

You can use the FOIL rule or the box method to expand out (x-4)(x-1) to get x^2-4x-1x+4 = x^2-5x+4 again. This confirms we have the proper factorization.

In one year, Angelica's height went from 52 inches to 56 inches what was the percent of increase in Angelica's height

AleksandrR [38]

Answer: 7.7%

Step-by-step explanation: First find the increase in height by subtracting 52 from 56. 56-52=4.

To find what percent this is of 52, divide 4 by 52. 4/52=0.0769. Then convert this from a decimal to a percent by multiplying by 100. 0.0769*100=7.69.

I just rounded it to the nearest tenth, you can change it how you need to.

What is 4 to the 2/3 power

Anna11 [10]

$\bf a^{\frac{{ n}}{{ m}}} \implies \sqrt[{ m}]{a^{ n}} \qquad \qquad
\sqrt[{ m}]{a^{ n}}\implies a^{\frac{{ n}}{{ m}}}\\\\
-------------------------------\\\\
4^{\frac{2}{3}}\implies \sqrt[3]{4^2}\implies \sqrt[3]{(2^2)^2}\implies \sqrt[3]{2^4}\implies \sqrt[3]{2^{3+1}}\implies \sqrt[3]{2^3\cdot 2}
\\\\\\
2\sqrt[3]{2}$

A basket of fruit contains 4 bananas, 3 apples, and 5 oranges. You intend to

Julli [10]

draw 1 : 4/12 = 1/3

draw2 : 3/11

draw 3 : 5/10 = 1/2

so probability to have : 1 banana then 1 apple then 1 orange is : 1/3*3/11*1/2 = 3/66 = 3*1 / 2*3*11 = 1/22
