Whats 2+2x (7/7)= to

1 answer:

fomenos3 years ago

5 0

Answer:

2+2x(7/7)= 0 (you do what's in the parenthesis first)

2+ 2x (1) =0 (then you multiply, and anything times 1 is itself)

2 + 2x= 0 (subtract 2 from both sides to get the x-term alone)

2x= -2 (divide both sides by 2 to get x isolated)

x= -1 (is your answer)

If the each side of equalaterial triangle is a cm. what is the area?

Yuri [45]

Step-by-step explanation:

$area \: of \: a \: triangle = \frac{1}{2} \times base \times height \\ \\ base = \frac{a}{2} cm \\ {h}^{2} + {( \frac{a}{2} )}^{2} = {a}^{2} \\ \\ h = \sqrt{ {a}^{2} - \frac{ {a}^{2} }{4} } \\ \\ area \: of \: triangle = \frac{1}{2} \times b \times h \\ = \frac{1}{2} \times \frac{a}{2} \times \sqrt{ {a}^{2} - \frac{ {a}^{2} }{4} } \\ \\ = \frac{a}{4} \times \sqrt{ {a}^{2} - \frac{ {a}^{2} }{4} }$

4. Lizette said this is correct. Is she right? Explain your answer to this question for

Maslowich

Answer:

Please check the explanation!

Step-by-step explanation:

Given the expression what Lizzet said was correct

$6^3\times \:\:3^6=18^8$

No, she is not right. Let me solve the expression

Let us solve the expression

$6^3\times \:\:3^6$

$=\left(3\times \:2\right)^3\times \:3^6$

$\mathrm{Apply\:exponent\:rule}:\:\:\:\left(ab\right)^c=a^cb^c$

$=3^3\times \:2^3\times \:3^6$ ∵ $\left(3\times \:2\right)^3=3^3\times \:2^3$

$\mathrm{Apply\:exponent\:rule}:\:\:a^b\times \:\:a^c=a^{b+c}$

$=2^3\times \:3^{3+6}$ ∵ $3^3\times \:3^6=\:3^{3+6}$

$=2^3\times \:3^9$

Therefore, the correct expression will be:

$6^3\times \:\:3^6=2^3\times \:\:3^9$

which can be further simplified such as:

$6^3\times \:\:3^6=2^3\times \:\:3^9$

$=8\times \:19683$

$=157464$

Can anyone help please

NeTakaya

Answer:

x = 0, x = $\frac{3}{2}$

Step-by-step explanation:

Given

8x² - 12x = 0 ← factor out 4x from each term

4x(2x - 3) = 0

Equate each factor to zero and solve for x

4x = 0 ⇒ x = 0

2x - 3 = 0 ⇒ 2x = 3 ⇒ x = $\frac{3}{2}$
