If 4·10= 40 then 4·-10 would equal -40 bc a positive times a negative equals a negative.

Hope this helped!!

Degger [83]

Answer:

45000 + 2500x = 54000 + 1500x

Step-by-step explanation:

Jerry has a new job and earns a salary of $45,000 and she will receive a salary increment of $2500 per year.

Now, Victoria has a new job and earns a salary of $54,000 and she will receive a salary increment of $1500 per year.

If after x years their salary becomes the same, then

45000 + 2500x = 54000 + 1500x

⇒ 1000x = 9000

⇒ x = 9 years. (Answer)

Rewrite each expression by completing the square q^2+12q+32

julia-pushkina [17]

The given expression can be written as $q^{2} +12q+32$ = (q+8)(q+4).

Step-by-step explanation:

Given,

$q^{2} +12q+32$

To make it a complete square.

Formula

(a+b)² = $a^{2} +2ab+b^{2}$

$a^{2} -b^{2} = (a+b)(a-b)$

Now,

$q^{2} +12q+32$

= $q^{2} +2.q.6+6^{2} -6^{2} +32$

= (q+6)²-36+32

= (q+6)²-4

= (q+6)²-2²

= (q+6+2)(q+6-2)

= (q+8)(q+4)

Solve the triangle. Round your answers to the nearest tenth.

butalik [34]

The missing information of the triangle is C = 63°, b ≈ 28.084 and c ≈ 25.084. (Correct choice: C)

<h3>How to determine the missing sides and angles</h3>

In this question we have a triangle with a known <em>side</em> lengths and two known <em>angle</em> measures. First, we find the missing angle by <em>Euclidean</em> geometry:

C = 180° - 94° - 23°

C = 63°

Lastly, we determine the <em>missing</em> sides by law of sines:

$b = 11 \times \frac{\sin 94^{\circ}}{\sin 23^{\circ}}$

b ≈ 28.084

$c = 11 \times \frac{\sin 63^{\circ}}{\sin 23^{\circ}}$

c ≈ 25.084

The missing information of the triangle is C = 63°, b ≈ 28.084 and c ≈ 25.084. (Correct choice: C)
