The formula for the eres of a triangle is A=2/1bh what is h equal to in terms of a and b

Kisachek [45]

Actually the formula for the area of a triangle is A = 1/2bh.

First step: multiply both sides by 2, to get rid of the 1/2.

2A = bh

Now divide both sides by b.

2A/b = h or h = 2A/b

A line goes through the point (–4,–2) and has an x-intercept of –1.

Keith_Richards [23]

Answer:

y = - x - 6

Step-by-step explanation:

y = mx + b

m = - 1

y = - x + b

(- 4, - 2)

- 2 = - (-4) + b

-2 = 4 + b

b = - 6

y = - x - 6

If m = 5 and n = -2, evaluate 3m - 4n and n2 - m and find the product of the two expressions.

ddd [48]

Hence the correct answer is C) -23

Further explanation:

We have to put the values of m and n into both expression first separately and then multiply the answers.

Given expressions are:

$Exp\ 1:3m-4n\\Exp\ 2: n^2-m$

The values are:

$m=5\\n=-2$

Putting the values in expression 1:

$3m-4n\\=3(5)-4(-2)\\=15+8\\=23$

Putting the values of m and n in second expression

$n^2-m\\=(-2)^2-5\\=4-5\\=-1$

Multiplying both expressions:

$(3m-4n)(n^2-m)=23* (-1)=-23$

Hence the correct answer is C) -23

How does 2π/4 simplify to π/4?

lana [24]

It doesn't
remember that
(x/g) times (y/z)=(x time y)/(g times z) so
2pi/4=(2 times pi)/(4 times 1) so
2pi/4=2/4 times pi/1=1/2 times pi/1=pi/2
