Question 7 (7 points) The length of the base of an isosceles triangle is x. The length of a leg is 2x-2.
The perimeter of the triangle is 31. Find x.

What are the soultion(s) to the quadratic equation 40- x^2=0

Consider circle c with angle acb measuring 3/4 radians.if minor arc ab measures 9 inches, what is the length of the radius of circle c? if necessary, round your answer to the nearest inch.

The value of x in this system of equations is 1. 3x + y = 9 y = –4x + 10 substitute the value of y in the first equation: combine like terms: apply the subtraction property of equality: apply the division property of equality: 3x + (–4x + 10) = 9 –x + 10 = 9 –x = –1 x = 1 what is the value of y?
