14 a cart loaded with 12 boxes weighs a total of 200
pounds,
• the empty cart weighs 25 pounds.
• each box weighs x pounds.
which equation can be used to find the weight of
one box?
a
b
c
d
121 + 25 = 200
12 + 25x = 200
12. + 25x = 200
12 + 25 + x = 200

It’s 12 +25+x=200 x is the variable for the other amount of charts and the 12 is for the other charts and the 25 is how much the cart weighs without a thing inside

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
