(3x^3-4x^2-5x+3)+(-4 - 6x^3+x^2 - 5x+5)
= 3x^3 - 4x^2 - 5x + 3 - 4 - 6x^3 + x^2 - 5x + 5
= -3x^3 - 3x^2 - 10x + 4

A rectangle is to be drawn with perimeter 64cm. If the length is to be 14cm more than the width, determine the are of the rectan

Vikentia [17]

P = 64 cm

2(( x + 14) + x) = 64

2x + 28 + 2x = 64

4x + 28 = 64

4x = 64 - 28

4x = 36

x = 36/4

x = 4

width = 4

lenight = 18

area = l x b

area = 18 x 4

area = 72

If triangle STR ~ triangle PTQ, find QT

lana [24]

Answer:

QT = 45

Step-by-step explanation:

ST = 65

SP = 26

RQ = 30

QT = 4x - 3

Given that ∆STR is similar to ∆PTQ, therefore:

$\frac{ST}{PT} = \frac{RT}{QT}$

Plug in the values

$\frac{65}{65 - 26} = \frac{30 + (4x - 3)}{4x - 3}$

Solve for x

$\frac{65}{39} = \frac{30 + 4x - 3)}{4x - 3}$

$\frac{5}{3} = \frac{27 + 4x}{4x - 3}$

Cross multiply

$5(4x - 3) = 3(27 + 4x)$

$20x - 15 = 81 + 12x$

Collect like terms

$20x - 12x = 81 + 15$

$8x = 96$

Divide both sides by 8

$x = \frac{96}{8}$

$x = 12$

✅QT = 4x - 3

Plug in the value of x

QT = 4(12) - 3 = 48 - 3

QT = 45

10 PTS!!!! PLEASE HELP ALGEBRA 1 MATH

Alex787 [66]

Parallel lines will always have the same SLOPE. In the case of this equation, the slope is $1$ since $x$ is the same as $1x$ and the coefficient of $x$ is the slope. Because there is no $y$ , the graph of the equation will NEVER intercept the y-axis. Therefore, whatever answer option does not have $y$ is correct.

Answer: C. $x=2$

Here's the graph to help you visualize:
