Answer:

-6+3[tex]\sqrt{2}[/tex] and -6-3[tex]\sqrt{2}[/tex]

Step-by-step explanation:

xy = 18

x+y = -12

y = -12-x

substitution method:

x(-12-x) = 18

-12x - x² - 18 = 0

-x² - 12x - 18 = 0

-(x² + 12x + 18) = 0

used quadratic formula:

(-12±√144 - 4(18)) ÷ 2

(-12 ± [tex]\sqrt{72}[/tex]) ÷ 2

(-12 ± 6[tex]\sqrt{2}[/tex]) ÷ 2

= -6 ± 3[tex]\sqrt{2}[/tex]

Answer:

The presence of many unpaired electrons in the valence shell of an atom enables it to form multiple bonds with other atoms. The paired electrons present in the valence shell do not take participate in the formation of chemical bonds as per the valence bond theory.

Answer:

f(x) is another way of saying "y", but when x is replaced with a number, it just means that x = that number.

Since A says to find f(7), it means that in this scenario, x = 7. So, 2x - 5 is turned into 2(7) - 5, which equals 14 - 5, which equals 9.

So, f(7) = 9.

You can then apply this to the rest of the numbers you are given.

I hope this helps! :)

Answer:94 m^2

Step-by-step explanation:

surface area equation for rectangle is 2*(a*b + a*c + b*c)

where a=4 b=5 and c=3

so substitute in all numbers and get:

Surface Area = 2×(4×5 + 4×3 + 5×3)

do the maths and got a solid 94 meters

(I squared because in this equation you are multiplying numbers that equal the area of a surface and not the whole volume which would be cubed)

Answer:

The answer is 30c^3y

Step-by-step explanation:

The LCM is the smallest number that all the numbers can divide in.

p ² + 6 is even if p ² is even (the sum of two even numbers is even), and this happens only if p itself is even, i.e. if p = 2 since 2 is the only even prime.

All other primes p are odd, so p ² would be odd, and adding 6 would not change that (odd + even = odd).

The statement (D) "the fewest students prefer black Model A1 calculators" is correct.

It is defined as the frequency that can be evaluated by the two-way frequency table. Usually, we can obtain this frequency by dividing the frequency that is not in the total frequency cell to total frequency.

There is the fewest value is 0.05

More students prefer Model C3 calculators than Model A1 calculators, mathematically,

0.30 > 0.45 (false)

More students prefer black calculators than white calculators, mathematically,

0.35 > 0.65 (false)

Similarly, statement third is also false.

Thus, the statement (D) “the fewest students prefer black Model A1 calculators” is correct.

Answer: [tex]4.14\ \text{pints}[/tex]

Step-by-step explanation:

Given

Keiko uses 6.9 Pints of blue and white paint

If the fraction of blue paint is [tex]\frac{2}{5}[/tex], then thr fraction of white paint is

[tex]1-\dfrac{2}{5}=\dfrac{3}{5}[/tex]

Amount of white paint is

[tex]\Rightarrow \dfrac{3}{5}\times 6.9=4.14\ \text{pints}[/tex]

The value of z in the given arrangement is 2 m.

Similar triangles are the triangles that look similar to each other, but their sizes might not be exactly the same.

Also,

Two triangles are said to be similar if their corresponding angles are congruent and the corresponding sides are in proportion.

Given that, an engineer needs to find the length of a beam to support the beam holding the wall, the two beams are perpendicular to one another, and a=4 m and b=1 m, we need to find z.

So, here we will use the concept of similar triangles,

According to the definition the corresponding sides are in proportion.

So, we get,

z/a = b/z

z² = 4

z = 2

Hence, the value of z in the given arrangement is 2 m.
