Mathematics
1 answer:
Pepsi [2]3 years ago
7 0

Answer: None of these answers are correct; tell this to your teacher. The 1st answer is closest to correct.

Step-by-step explanation:

The second and fourth answers are not viable because expanding them would result in x^3 which is not in the original equation.

1. 5x(x+3)-2(x+3)

5x^2+13x-6, This answer is closest to correct and may be correct in the case of a typo.

3. 5x(x-3)-2(x-3) ; Expand

5x^2-15x - 2x +6

5x^2-17x+6

In the parallelogram PQRS

  • PS = 5  and ∠Q  = 105
<h3>What is defined as the parallelogram?</h3>
  • A parallelogram is a type of quadrilateral created by parallel lines.
  • A parallelogram's angle between adjacent sides can vary, however the opposite sides must be parallel in order to be a parallelogram.
  • A parallelogram is formed when the opposite sides of a quadrilateral are parallel as well as congruent.

For the given question;

In the parallelogram PQRS,

QR = PS = 5 (opposite side of parallelogram are parallel and equal).

Sum of all angles is 360.

∠Q =  ∠S (opposite angles of parallelogram are equal)

∠P + ∠Q + ∠R + ∠S = 360

2∠P + 2∠Q = 360

2∠Q  = 360 - 2∠P

  • 2∠Q  = 360 - 150

2∠Q  = 210

∠Q  = 105

Thus, the angle Q is found as 105 degrees.

In a four year period, about 80,000 acres of coastal wetlands in the United States are lost each year. What integer represents t
klemol [59]

Answer:

-320000

Step-by-step explanation:

Given

Lost Land = 80,000 acres yearly

Duration 4 years

Required

The total change

Represent the total change with y;

y is calculated as thus;

y = Lost\ Land * Duration

y = -80,000 acres * 4

y = -320000\ acres

<em>Hence, a total of 320000 acres were lost during the period</em>

Solve the following inequality: 6x - 9 ≥ 11x - 17.
Juli2301 [7.4K]

Answer:

x ≤8/5

Step-by-step explanation:

6x - 9 ≥ 11x - 17

Subtract 6x from each side

6x -6x-9 ≥ 11x - 17-6x

-9 ≥ 5x- 17

Add 17 to each side

-9+17≥ 5x - 17+17

8≥ 5x

Divide each side by 5

8/5≥ 5x /5

8/5≥ x

Use the remainder theorem to determine the remainder when 3t²+5t-7 is divided by t-5
Brrunno [24]
f(t)=3t^2+5t-7\implies f(5)=3(5)^2+5(5)-7=93

which means the remainder upon dividing f(t) by t-5 is 93.

This is because we can write

\dfrac{f(t)}{t-5}=q(t)+\dfrac{r(t)}{t-5}

where q(t) is the quotient and r(t) is the remainder. Multiplying both sides by t-5, then evaluating at t=5 makes the q(t) term vanish, leaving the remainder:

f(t)=q(t)(t-5)+r(t)\implies f(5)=r(5)
