Name the like terms in the expression 5a + 8 – 3a + 11.

The like terms are 5a and -3a. Also, 8 and 11 are like terms

8 and 11 are like terms because they both are constants and don't have a variable.
5a and 3a are like terms because they both have the variable a in common. 
you would combine these like terms
5a + 8 - 3a + 11
(5a - 3a) + (8 + 11)
2a + 19

Hope this helps :)

The like terms in this are

5a
3a

Intersecting secant-tangent theorem states that if a tangent segment and a secant segment are drawn to a circle from an exterior point, then the square of the measure of the tangent segment is equal to the product of the measures of the secant segment and its external secant segment.so to break it down: 1. pq acts as the tangent and ps as the secant with an intersection at p.sr = 21rp = 3x + 3pq = 4x + 4following to equation: tangent squared = the two segments multiplied by each otherso (4x + 4) ^ 2 = (3x + 3) • (21) simplifies to 16x^2 - 31x - 47 = 0 or (16x - 47)(x + 1) x = -1 or x = 47/162. pq acts as the tangent and ps as the secant with an intersection at p (again! )sr = 16rp = xpq = 15(15) ^ 2 = 16 • x225 = 16xx = 225/163. the interesting chords are proportional to each other so a ratio is possible to set up: ap dp 10 3 + x = = —— = pc pb 8 xcross multiple to get 10x = (3 + x)(8)x = 12
