Step-by-step explanation:

(4x+7)(2x+5)

We would have to multiply each term in the first bracket by the term in the second bracket.

4x(2x+5)+7(2x+5)

So now we multiply 4x by 2x and 5

8x+10x

8x+10x+7(2x+5)

And then we multiply 7 by the 2x and the 5

14x+35

8x+10x+14x+35

So now we proceed to add since like terms have already been combined

18x+14x+35

32x+35

Given the kite below, if NO = 5 and OM = 12, what is the value of NM?

tester [92]

Answer:

NM = 13

Step-by-step explanation:

pythagorean theorem: $a^{2} + b^{2} = c^{2}$

a or NO = 5

b or OM = 12

c or NM = ?

plug in what is known:

⇒ $5^{2} + 12^{2} = c^{2}$

⇒ $25 + 144 = c^{2}$

⇒ 169 = $c^{2}$

square root each side of the equation:

⇒ $\sqrt{169} = \sqrt{c^{2} }$

solve:

⇒ 13 = c
