Answer:
x=7
Step-by-step explanation:
2x+3(x-1)=3x+11
___________________________________________
2x+3x-3=3x+11
-2x -11 -2x -11
-7=1x
x=7
Answer:
The GCF of 42 and 55 is 1.
Step-by-step explanation:
sorry it took me a while to write in my book
42 AND 55 ARE A PAIR OF CO-PRIME NUMBERS
CO PRIME:a pair of numbers which have the only common factor as 1 is called as co prime
28.49 because they dont have a proportion
Answer:
∠Q = 75 °
Step-by-step explanation:
Since PR = PQ then Δ PQR is isosceles and the base angles are congruent, that is
∠R = ∠Q = 2x + 15
The sum of the 3 angles in a triangle = 180°
Sum the 3 angles and equate to 180
2x + 15 + 2x + 15 + x = 180, that is
5x + 30 = 180 ( subtract 30 from both sides )
5x = 150 ( divide both sides by 5 )
x = 30
Hence
∠Q = 2x + 15 = (2 × 30) + 15 = 60 + 15 = 75°
Answer:
<h3>-9p²+6p+2/4p²</h3>
Step-by-step explanation:
Given the expression
(p ^ 2 + 6p + 2)/(4p ^ 2) - (10p ^ 2)/(4p ^ 2)
Find the LCM
The LCM = 4p²
[p²+6p+2 - (10p²)]/4p²
Expand
p²-10p²+6p+2/4p²
-9p²+6p+2/4p²
hence the required expression is -9p²+6p+2/4p²
