I need someone to check these answers ASAP.

Reptile [31]

Alright, 1, 2, and 4 are correct but 3 is not.

The error you made could be hard to notice but it was made. So let's put the equation up, 6x-(2x-9)=-31. Your error occurred when you didn;t distribute the negative sign for (2x-9), if you woud have distributed it then the equation would then be simplified into 6x-2x+9=31. You then add like terms and get 4x+9=31, subtract 9 on both sides and you'll get 4x=22. Divide 4 on both sides to isolate the variable and you get x=5.5

What is the area of the rectangle

Eddi Din [679]

Answer:

B) $\frac{15}{4}$

Step-by-step explanation:

Area of a rectangle formula:

A = bh

Given:

b = $2\frac{1}{2}$

h = $1\frac{1}{2}$

Work:

A = bh

A = $(2\frac{1}{2} )(1\frac{1}{2} )$

A = $\frac{15}{4}$

Help me it’s urgent

Ket [755]

Answer:

$a_1 = -\dfrac{3}{4}$

Step-by-step explanation:

$a_1 \times r = a_2$

$a_1 \times r^2 = a_3$

$a_1 \times r^3 = a_4$

...

$a_1 \times r^8 = a_9$

$\dfrac{a_9}{a_4} = \dfrac{a_1 \times r^8}{a_1 \times r^3} = \dfrac{-196}{6}$

$r^5 = -32$

$r = -2$

$a_1 \times r^3 = a_4$

$a_1 \times (-2)^3 = 6$

$a_1 = \dfrac{6}{-8}$

$a_1 = -\dfrac{3}{4}$
