Is known that

(a + b)² = a² + 2.a.b + b²

So:

(x + 4)² = x² + 2.x.4 + 4² = x² + 8x + 16

Answer: x^2 +8x +16
Explanation:
each term in the second bracket must be multiplied by each term in the first bracket
⇒(x +4)^2=(x+4)(x+4)⇒(x+4(x+4)
=x(x+4)+4(x+4)
=(x×x)+(x×4)+ (4×x)+(4×4)
=x2+4x+4x+16
=x^2+8x+16

That's all

Write a equation of the line below

taurus [48]

Answer: y=1/2 - 3

Step-by-step explanation:

what they want you to find is the slope and y-intercept, and put that into slope-int form, which is y=mx+b. the point that is located on the y intercept is (0, -3), which gives you your b, which is -3. the other point on the graph helps you find the rise/run, or slope, which is m=2/4. simplified is m=1/2. so, y=1/2 - 3

Two supplementary angles differ by 34. Find the angles.

erastovalidia [21]

Answer:

x=107,y=73 is ur answer

Step-by-step explanation:

let two angles be x & y

x-y=34(given)

x=34+y................1

x+y=180(supplementary)

putting the value of x

34+y+y=180

2y=180-34

y=146/2=73

:.y=73

putting the value of y in equation 1

x=34+73=107

:.x=107
