Hello!

<h2>Answer:</h2><h2 />

<h2>___________________________________</h2><h2>Explanation: </h2>

4(2x+y)-3(x+y)

Multiply everything inside the brackets by the number outside.

Answer:

5x + y

Step-by-step explanation:

4(2x + y) - 3(x + y) = 4*2x + 4y - 3x - 3y = 8x - 3x + 4y - 3y = 5x + y

Answer: c)

Step-by-step explanation:

This can be done through trial-and-error. Use the pythagoreas' theorem $a^{2} +b^{2} =c^{2}$ and if the left side of the equation is equal to the right, that is the answer.

(Do take note that c is the longest side.)

$0.07^{2} +2.4^{2} =5.7649$

$2.5^{2}=6.25$

Since $2.5^{2} \neq 5.7649$ , a) is wrong.

$17^{2} +30^{2} =1189\\
34^{2} =1156$

Since $34^{2}\neq1189$ , b) is wrong.

c) (answer)

$5^{2} +12^{2} =169\\13^{2} =169$

Since $13^{2} =169$ , c) is correct.

$(7x)^{2} +(12x)^{2} =193x^{2}\\(13x)^{2} =169x^{2}$

Since $(13x)^{2} \neq193x^{2}$ , d) is wrong.

Use addition properties and strategies to find the sum..1.)34+62+51+46=? 2.)27+68+43=? 3.)42+36+18=? 4.)74+35+16+45=?

erica [24]

1.
$34 + 62 = 96 + 51 = 147$
$147 + 46 = 193$

2.
$27 + 68 = 95 + 43 = 138$
3.
$42 + 36 = 78 + 18 = 96$
4.
$74 + 35 = 109 + 16 = 125 + 45 =$
$= 70$
