Step-by-step explanation:
you multiply the number of lemonades by 1.80 because you're just basically adding 1.80 from each lemonade you sell
<h3>Given</h3>
... f(x) = x² -4x +1
<h3>Find</h3>
... a) f(-8)
... b) f(x+9)
... c) f(-x)
<h3>Solution</h3>
In each case, put the function argument where x is, then simplify.
a) f(-8) = (-8)² -4(-8) +1 = 64 +32 + 1 = 97
b) f(x+9) = (x+9)² -4(x+9) +1
... = x² +18x +81 -4x -36 +1
... f(x+9) = x² +14x +46
c) f(-x) = (-x)² -4(-x) +1
... f(-x) = x² +4x +1
1: Almost all rocks are made of minerals but, different rocks have different kinds of minerals.
2: Sedimentary, metamorphic, and igneous.
3: Weathering is breaking down of the rocks, soil, and minerals as well as artificial materials through contact with the Earth's atmosphere, biota and water.
4: i don't know this one sorry :(
5: Metamorphic Rocks
6: Geological Society
7: Igneous Rocks. They are about 3ft long!
8: Foliated Metamorphic Rocks
9:Phaneritic Igneous Rock
I hoped this helped! :) sorry for not knowing number 4 :( Have a good day! :)
Louise’s answer is not correct. She is missing the term 30x3. When squaring a binomial, it is best to write the product of the binomial times itself. Then you can use the distributive property to multiply each term in the first binomial by each term in the second binomial. Louise also could have used the formula for a perfect square trinomial, which is found by squaring a binomial.
If you would like to simplify (5 * p^2 - 3) + (2 * p^2 - 3 * p^3), you can calculate this using the following steps:
(5 * p^2 - 3) + (2 * p^2 - 3 * p^3) = 5 * p^2 - 3 + 2 * p^2 - 3 * p^3 = - 3 * p^3 + 7 * p^2 - 3
The correct result would be - 3 * p^3 + 7 * p^2 - 3.
