Area = (x+6)(x+2) = x^2 + 8x + 12
Answer:
Check explanation.
Step-by-step explanation:
slope-intercept form: y=mx+b
9x+5y=23
5y=-9x+23
y=-9/5x+23/5
m=slope: -9/5
b=y-intercept: 23/5
Answer:
x = 6 sqrt(3)
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
6^2+ x^2 = 12^2
36 + x^2 = 144
Subtract 36 from each side
x^2 = 144-36
x^2 =108
Take the square root of each side
sqrt(x^2) = sqrt(108)
x = sqrt(36*3)
x = 6 sqrt(3)
Answer:
Step-by-step explanation:
1,8
5,7
2,3
X= -1 beacuse negative one plus one is 0 and that will equal zero for both sides
