B. 33

Multiply the base times the height and divide by two to find the area of a triangle.

(b•h) /2 = x
(22•3) /2 = 33

Answer:

The answer is B.

Step-by-step explanation:

You have to apply the area of triangle formula :

area =  \frac{1}{2}  \times base \times height

let \: base = 22 \\ let \: height = 3

area =  \frac{1}{2}  \times 22 \times 3

area = 11 \times 3

area = 33 \:  {units}^{2}

A 32% discount (descuento) would come to 0.32(MX$2,500) = MX$800.

Subtracting MX$800 from MX$2,500 yields MX$1,700.

Alicia pagara MX$1,700.

The graph of g(x) resembles the graph of f(x)=x^2, but it has been changed. Which of these is the equation of g(x)?
siniylev [52]

Answer:

A.

Step-by-step explanation:

Anwer A has the following equation:

g(x)=\frac{3}{5}x^2-3

In this equation, we can calculated the intercept replacing x by 0, as:

g(x)=\frac{3}{5}0^2-3=-3

if this is the answer, the graph of g(x) should be through the point (0,-3) and that happens.

Additionally, the roots of the equations are calculated replacing g(x) by 0 and solving for x, so:

0=\frac{3}{5}x^2-3\\x_1=\sqrt{5}=2.236\\x_2=-\sqrt{5}=-2.236

It means that the graph of g(x) should be through the points (2.236,0) and (-2.236,0) and that happens too.

So, the answer is A, g(x)=\frac{3}{5}x^2-3

given B is the midpoint of line CE, Angle C is congruent to angle E. prove angle a is congruent to angle D ​
ser-zykov [4K]

Answer:

  see below

Step-by-step explanation:

The ASA congruence postulate is being invoked, so you're looking to show two angles and the side between them are congruent.

_____

Personally, I'd go at it differently. I'd say that alternate interior angles ∠C≅∠E means AE║CD, so ∠A≅∠D because they're alternate interior angles. B does not need to be a midpoint for this proof.
