Answer:
Answer:
B only
Step-by-step explanation:
In A and in C, only the angles of
one triangle are congruent to the
corresponding angles of the other
triangle. That proves similar triangles but
not necessarily congruent triangles.
Definition of congruent triangles:
Two triangle are congruent if all angles
of one triangle are congruent to all
corresponding angles of the other
triangle and all sides of one triangle are
congruent to all corresponding sides of
the other triangle.
That happens only with the triangles in B.
Answer: B only
Answer:
1.4 (or 7/5)
Step-by-step explanation:
5x = 7
/5 /5
x = 1.4
Answer:
18x² - 6x
Step-by-step explanation:
Differentiate using the product rule, that is
y = f(x)g(x), then
= f(x)g'(x) + g(x)f'(x)
here
f(x) = 3x² ⇒ f'(x) = 6x
g(x) = 2x - 1 ⇒ g'(x) = 2, thus
(3x²(2x - 1)
= 3x² × 2 + 6x(2x - 1)
= 6x² + 12x² - 6x
= 18x² - 6x

Answer:
Step-by-step explanation:
Let g and b represent the numbers of candy canes the girl and boy have, respectively.
g -1 = b +1 . . . . . . girl gives to boy, they're equal
g +1 = 2(b -1) . . . . boy gives to girl; she has double
Adding 1 to the first equation gives an expression for g that can be substituted into the second equation.
g = b +2
(b +2) +1 = 2b -2
5 = b . . . . . . . . . . add 2-b, simplify
g = 5+2 = 7 . . . . . find g
The girl has 7 candy canes; the boy has 5.
