Dan factored x^2+121 into (x+1-11)

babunello [35]

Answer:

Your question is a little unclear. If you are just trying to factor x² + 121, it's prime. (can't be factored using real numbers).

Step-by-step explanation:

The difference of two squares is a special form. a² - b² = (a+b)(a-b).

But, the sum of two squares is prime. a²+ b² cannot be factored.

Age If you add Natalie's age and Fred's age, the result is 43. If you add Fred's age to 4 times

Len [333]

Let’s take fred age as x and Natalie’s age as y.
So,
A/Q
X + Y = 43. Let it be eqution 1
and
X + 4Y = 79. Let it be equation 2

Combining equation 1 and 2, we get

( X + Y) + 3Y = 79
43 + 3Y = 79
3Y = 36
Y = 12

Now, evaluating the value of Y in equation 1 we get,

X + 12 = 43
X = 31

Therefore, Fred is 31years old and Natalie is 12 years old.

Miguel’s employer pays $1,825 in health insurance and $93 in life insurance per year. He also gets $2,860 in paid time off per y

LuckyWell [14K]

Answer:

the correct answer is option A

Step-by-step explanation:

given,

Health insurance payment = $1,825

Life insurance per year = $ 93

paid off per year = $2,860

monthly gross pay is = $3,890

Miguel's get paid yearly =health insurance + life insurance + paid time off

= 1825 + 93 + 2860

= $ 4778

his monthly gross pay = $ 3,890

his yearly gross pay = $ 3,890 ×12

= $ 46,680

hence total job benefit = $ 46,680 + $ 4778

= $51,458

so , the correct answer is option A

Which statement is true about a circle? A. A circle's area and circumference are always equal B. A circles area and circumferenc

Nuetrik [128]

Answer:

Option D. A circles area and circumference are only equal when the radius is 2 units.

Step-by-step explanation:

we know that

The area of circle is equal to

$A=\pi r^{2}$

The circumference of a circle is equal to

$C=2\pi r$

equate both formulas

$\pi r^{2}=2\pi r$

simplify

$r^2=2r\\r=2$

therefore

A circles area and circumference are only equal when the radius is 2 units.
