Answer:
24. 8 x 3.....................
Answer:(gf)(3)=g(3)f(3) g(a)=3a+2 or g(3)=3(3)+2=9+2 =11 f(a)=2a−4 f(3)=2(3)−4=6−4=2 g(3)f(3)=112. Answer
Step-by-step explanation:
Answer:
16x^2 + 9x^2 + 9x + 13.
Step-by-step explanation:
6x^3 + 8x^2 – 2x + 4 +10x^3 + x^2 + 11x + 9
Bringing like terms together:
= 6x^3 + 10x^3 + 8x^2 + x^2 - 2x + 11x + 4 + 9
= 16x^2 + 9x^2 + 9x + 13. (answer).
Answer: "No, the triangles are not necessarily congruent." is the correct statement .
Step-by-step explanation:
In ΔCDE, m∠C = 30° and m∠E = 50°
Therefore by angle sum property of triangles
m∠C+m∠D+m∠E=180°
⇒m∠D=180°-m∠E-m∠C=180°-30°-50°=100°
⇒m∠D=100°
In ΔFGH, m∠G = 100° and m∠H = 50°
Similarly m∠F +∠G+m∠H=180°
⇒m∠F=180°-∠G-m∠H=180°-100°-50=30°
⇒m∠F=30°
Now ΔCDE and ΔFGH
m∠C=m∠F=30°,m∠D=m∠G=100°,m∠E=m∠H=50°
by AAA similarity criteria ΔCDE ≈ ΔFGH but can't say congruent.
Congruent triangles are the pair of triangles in which corresponding sides and angles are equal . A congruent triangle is a similar triangle but a similar triangle may not be a congruent triangle.
five to the second power is 5x5 which is 25.
two to the fifth power is 2x2x2x2x2 which is 32.
