Giving brainliest for correct awnser. Factor the expression below. <br>​
tresset_1 [31]

Answer:

B. (x + 3) (x + 27)

Step-by-step explanation:

<em><u>To factor the expression, you must split the middle term (18x) into two terms that can be added to get 18, and multiplied to get 81:</u></em>

<em><u /></em>x^2 + 18x + 81

x^2 +3x + 27x + 81

<em><u>Group:</u></em>

<em><u /></em>(x^2 +3x) (27x + 81)

<em><u>Take out GCF (Greates Common Factor):</u></em>

x(x + 3) 27(x + 3)

(x + 27) (x + 3)

andreev551 [17]

Answer:

Slope : The rate of increase of temperature on the earth's surface is 0.02°C per year since 1900.

T-intercept : 8.5 represents the temperature in °C of the earth's surface in the year 1900.

Step-by-step explanation:

The average surface temperature of Earth rising steadily. Scientists have modeled the temperature by the equation, T = 0.02t + 8.50 where t represents years since 1900 and T is the temperature in ◦C.

Now, the slope of the model equation is 0.02 which means the rate of increase of temperature on the earth's surface is 0.02°C per year since 1900.

Again, the T-intercept i.e. 8.5 represents the temperature in °C of the earth's surface in the year 1900. (Answer)
