Answer:

4y + 5x + 13

Step-by-step explanation:

4y + 3(y + 1) + 2(x+5)

Distribute

4y + 3y + (3 x 1) + 2x + (2 x 5)

4y + 3y + 3 + 2x + 10

Combine like terms

4y + 5x + 13

Answer:

The third side is 3√6 units.

Step-by-step explanation:

Given that this is a 90° triangle so you can apply Pythagoras Theorem :

${a}^{2} + {b}^{2} = {c}^{2}$

${a}^{2} = {c}^{2} - {b}^{2}$

${a}^{2} = {( \sqrt{90}) }^{2} - {6}^{2}$

${a}^{2} = 90 - 36$

${a}^{2} = 54$

$a = \sqrt{54} = \sqrt{9 \times 6} = 3 \sqrt{6}$

just plug it in and check— trust me, best trick in the book. for this one, there’s no need.

what is a term? it’s when the variable is on a constant— 3x

7. The steps below show Cam's work in solving an equation. Circle the line where he makes a mistake. Then, find the correct solu

Inessa05 [86]

Answer:

Error was at the fourth line: 12 = 16x

Correct solution: x = ½

Step-by-step explanation:

Let's solve the equation step by step to find the correct solution, and also, to find out at which line Cam made a mistake.

10 - 2x = 19x + 2 - 5x (given)

10 - 2x = 19x - 5x + 2

10 - 2x = 14x + 2

Add 2x to both sides

10 - 2x + 2x = 14x + 2 + 2x

10 = 14x + 2x + 2

10 = 16x + 2

Subtract 2 from both sides

10 - 2 = 16x + 2 - 2

8 = 16x (this is where Cam made an error, at the fourth line. He wrote: 12 = 16x. It seems Can only subtracted 2 from the right, then added 2 to the left. Subtraction property of equality was not properly done.)

Proceeding further with our calculation, we would divide both sides by 16

8/16 = 16x/16

½ = x

x = ½.

The diagram below represents the first three terms of a sequence. Assuming the pattern continues,which formula determines an, th

pishuonlain [190]

The correct answer is B) $a_n=3n+1$

Writing the sequence numerically, we have 4, 7, 10, ...

This is an arithmetic sequence, since there is a constant, 3, added each time. This gives us the explicit formula
$a_n=4+3(n-1)$

Using the distributive property, we have
$a_n=4+3*n-3*1
\\
\\a_n=4+3n-3$

Combining like terms, we have
$a_n=3n+1$
