Step-by-step explanation:

the area of the square is (x+2)^2 and the factored form of it is x^2+4x+4

since we know the area is = 7 therefore

x^2 + 4x +4 = 7 and x^2 + 4x = 3

if you want to find the value of x :

x^2+4x+4 = 7

x^2+4x -3 = 0

(x-3)(x-1)=0

x = 3 or

x = 1

there are 124 students in the band. there are 12 more boys than girls in the band. how many boys and how many girls are in the b
kvv77 [185]
B = g + 12
g + b = 124
Replace the b in the second equation with
g+ 12

g+ g+12=124
2g + 12 = 124
Subtract 12 from both sides
2g = 112
Divide by 2
g = 56

b= 56 + 12
b= 68

Let m be the slope:

m=(y₂-y₁)/(x₂-x₁)

solve for c:

1/6=(9-c)/(1-7)

1/6=(9-c)/-6

-1=9-c

-10=-c

c=10
