Answer:

x = 2\sqrt{35}

Step-by-step explanation:

Using Pythagoras' identity in the right triangle

x² + b² = a² , that is

x² + 2² = 12²

x² + 4 = 144 ( subtract 4 from both sides )

x² = 140 ( take the square root of both sides )

x = \sqrt{140} = \sqrt{4(35)} = 2\sqrt{35}

Alonzo's suitcase can weigh no more than 20 kilograms if he wants to take it on the airplane without paying a fee. His suitcase
Olegator [25]

Given: Alonzo's suitcase can weigh no more than 20 kilograms if he wants to take it on the airplane without paying a fee.

Let x denote the weight of suitcase, then

We know that 1 kg =10 hg

Therefore, 20kg=

⇒

Since, the weight of his suitcase is 220 hg.

The amount of weight will Alanzo have to take out of his suitcase to meet the weight limit will be :-

Hence, 20 hg of weight have to take out of his suitcase to meet the weight limit.

Multiply the trinomial x^2+xy+y^2 times the binomial x-y and simplify.
Natalija [7]
Multiply then simplify, that's doing the same work twice...anyway

x^3+x^2y+xy^2-x^2y-xy^2-y^3

x^3-y^3  which if factored is:

(x-y)(x^2+xy+y^2)  which is what you started with :)

* WILL GIVE BRAINIEST*
k0ka [10]

Answer:

B: 280

Step-by-step explanation:

The regression line predicts that when x equals 5:

log_{10}(y) = 2.447

In order to find the value for y, one must simply apply the following logarithmic property:

if : log_{b}(a) = c

then: b^c = a

Applying it to this particular problem:

log_{10}(y) = 2.2447\\10^{2.447}= y\\y=280

Therefore, the regression line predicts y will equal 280 when x equals 5.
