If x2 mx m is a perfect-square trinomial, which equation must be true?.
kodGreya [7K]

Expression consist of numbers, variables, and mathematical operations. The equation that is true is x²+mx+m= (x+2)².

<h3>What is an Expression?</h3>

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

As it is given that the x²+mx+m is a perfect square trinomial, and we know that the general equation of perfect square trinomial  is given as,

ax²+bx+c=0

where a,b and c are real numbers, and a≠0,

if we compare the equation with our equation

ax^2+bx+c=0\\x^2+mx+m=0

We will get the value of 'a' as 1, b=c=m, therefore, we need a binomial which is when expanded then in its perfect square trinomial the value of b=c, therefore, the only feasible option here is (x+2)².

Hence, the equation that is true is x²+mx+m= (x+2)².

The Earth's circumference measured at the equator is approximately 1.3148 × 108 feet. What is the number written in standard for
maks197457 [2]

Answer:

The number written in standard form is 131,480,000

Step-by-step explanation:

we have

1.3148*10^8

we know that

10^8=100,000,000

substitute

1.3148*10^8=1.3148(100,000,000)

Remember that

When multiplying decimals by 10, move the decimal point one space to the right

In this case move the decimal point eight spaces to the right

1.3148(100,000,000)=131,480,000

therefore

The number written in standard form is 131,480,000

If a is an odd integer and b is an even integer, which of the following makes an odd integer?
Serga [27]

9514 1404 393

Answer:

  D.) a+2b

Step-by-step explanation:

The integers 'a' and 'b' can be any, so you can choose a couple and evaluate these expressions to see what you get. For example, we can let a=1 and b=0. For these values, the offered expressions evaluate to ...

  A) 3(0) = 0 . . . even

  B) 1 +3 = 4 . . . even

  C) 2(1+0) = 2 . . . even

  D) 1 +2(0) = 1 . . . odd

_____

<em>Additional comment</em>

These rules apply to even/odd:

  • odd × odd = odd
  • odd × even = even
  • even × even = even
  • odd + odd = even
  • odd + even = odd
  • even + even = even

Then A is (odd)(even) = even; B is (odd)+(odd) = even; C is (even)(whatever) = even; D = (odd)+(even) = odd.
