If in triangles ABC and DEF, AB = DE, AC = DF, and angle A = angle D, then triangle ABC is congruent to triangle DEF. Using words: If 3 sides in one triangle are congruent to 3 sides of a second triangle, then the triangles are congruent.
Answer:
A) 9x^2-12x+4
Step-by-step explanation:
to find out whether an equation is a perfect square when we take the square root of "a" and the square root of "c" and double their sum. The result should be the middle term, -12
so
square root of 9; 3
square root of 4: 2
2((3*-2))=-12
now we can take the square root of 9x^2(which is 3x) and the square root of 4(-2) and put it in a expression like this
(3x-2)^2
hope this helps!
Answer:
b > 9
Step-by-step explanation:
6(b – 4) > 30
Divide each side by 6
6/6(b – 4) > 30/6
b-4 > 5
Add 4 to each side
b-4+4 > 5+4
b > 9
