Answer: The common difference is 7, and the next two terms are 19 and 26.

Step-by-step explanation:

Between -9 and -2 there is +7, same with between -2 and 5, as well as 5 and 12. Adding 7 to 12 again gets 19, and adding 7 to 19 gets 26 as well for the next two terms.

Answer:

$15.75 {cm}^{3}$

Step-by-step explanation:

Convert m to cm,

0.045m =4.5cm

0.034m = 3.5cm

0.01m = 1cm

Volume = 4.5 cm × 3.5 × 1 = 15.75 cm3

Int he figure below find AC

Ahat [919]

Given :-

Two triangles with their two angles equal .

To Find :-

Measure of AC .

Answer :-

Here in ∆ABC and ∆EDC ,

$\angle$ CAB = $\angle$ CED (given )
$\angle$ CBA = $\angle$ CDE (given)

Therefore by AA similarity criterion , we can say that ∆ABC ~ ∆EDC . Also we know that corresponding sides of similar triangles are proportional . So ,

→ AC/EC = BC/DC

→ AC/9 = 8/12

→ AC = 8/12 * 9

→ AC = 6

Hence the measure of side AC is 6 .

I hope this helps.

PLEASE ANSWERRRRRRRRRR

IceJOKER [234]

Answer:

C. (3, -2)

Step-by-step explanation:

x + y = 1 ➡ x = 1 - y we can use this information in the first equation to find the value of y

3x - 5y = 19 replace x with 1 - y

3 ×(1-y) - 5y = 19 ➡ 3 - 3y - 5y = 19 add like terms

-8y = 16

y = -2 if y is 2 then x is

x + y = 1 ➡ x +(-2) = 1 and x = 3
