Answer:

D. x=y+2z

Step-by-step explanation:

if you expand out the first equation (x) you will get: a^2+b^2+c^2+2ab+2bc+2ac

then looking at all of the choices, it can be seen that the third equation (z) needs to be multiplied by to get 2ab+2bc+2ac and then added to the second equation (y) which would result in D being the correct answer.

D. x=y+2z

Answer:

B) 43.758

Step-by-step explanation:

Starting from the right side of the decimal point, the places are:

tenths

hundredths

thousands

Each time, you add a zero to the previous number (10 to 100 to 1000, etc), therefore the third decimal would be the thousandths place. If the next figure is a 5 or above, you round up, to the next decimal.

Write: 3^-4 in standard form

pav-90 [236]

Answer:

$\frac{1}{81}$

Step-by-step explanation:

Key skills: Exponents + Fractions

Use the negative exponent property. If your number is x^-y then it would be the same as 1/x^y

3^-4 is the same as $\frac{1}{3^{4}}$

3^4 is 81, so your answer would be 1/81.

Hope you have a nice day and understood this!
