92° and 14 cm

Since the triangles are congruent then corresponding angles and corresponding sides are equal
∠B = ∠Q, hence
6x - 16 = 5x + 2 ( subtract 5x from both sides )
x - 16 = 2 ( add 16 to both sides )
x = 18, hence
∠B = (5 × 18 ) + 2 = 90 + 2 = 92°

Similarly PR = AC
9x - 4 = 6x + 2 ( subtract 6x from both sides )
3x - 4 = 2 ( add 2 to both sides and divide by 3 )
3x = 6 ⇒ x = 2
PR = (9 × 2 ) - 4 = 18 - 4 = 14 cm
Answer:
Step-by-step explanation:
x^2(3x - 7) + 2(3x - 7)
(x^2 + 2)(3x - 7)
Answer:
i say option (a) is the answer its correct.
Step-by-step explanation:
Answer:
(2,4)
Step-by-step explanation:
the x values stays the same because you are reflecting over its axis. the 4 becomes positive
Answer:
-7
Step-by-step explanation:
You use the quadratic formula of to get:
a = 1
b = 7
c = -13
then you plug that into x= (-b ± √b²-4ac)/(2a) :
x= ( -7 ± √7²- 4(1)(-13) )/(2(1))
The sum of these two x values turns out to be:
