Answer:

choice 4) right scalene (one right angle and the side opposite that angle is the longest side)

choice 1) obtuse isosceles (one angle greater than 90 degrees and 2 equal length legs)

Answer:

D. right scalene

B. obtuse scalene

Step-by-step explanation:

The reason for this is because, it has a right angle so therefore, it already can be only B or D. However isosceles talk about having two sides of equal length. This triangle does not therefore, it cannot be B. That means it can only be D. right scalene

You immediately know that it is a obtuse because of the way it looks and the fact that there is a 130 degrees angle in the triangle. Therefore, you only have A and B and since isosceles triangles have two equal acute angles that won't work. Therefore, your only answer would be obtuse scalene.

Right and solve an equation to find the number n.four times a difference of a number and seven is 12

amm1812

For this case we must propose an algebraic expression associated with:

"four times a difference of a number and seven is 12"

So we have to:

Four times a difference of a number and seven is represented as: $4 (n-7)$

So we have the expression is:

$4 (n-7) = 12$

We apply distributive property to the terms within parentheses:

$4n-28 = 12$

We add 28 to both sides:

$4n = 12 + 28\\4n = 40$

We divide between 4 on both sides:

$n = \frac {40} {4}\\n = 10$

Answer:

$n=10$

Rabiyas mother is tired so rabia decided iron her clothes but the ironing cloth herself but the ironing board is too high for he

xeze [42]

This is a guess, but, from what I've researched, maybe decrease? I've looked into it alot and that's just I think, though, it may depend on the previous height. Still, just an educated guess (I've got 100% on all kinds of quizzes because of educated guesses so, it may work!)

If LB = 6 and LN = 2x + 5 , what is x? Show your work.

olga nikolaevna [1]

Answer:

x=3.5

Step-by-step explanation:

MN is divided in half because of MO. BN would equal 6, too. In all, LN should equal 12. So, your equation would be:

2x+5=12

Solve this equation:

2x=12-5

2x=7

x=3.5

Which of these is a point-slope equation of the line that is perpendicular to y – 3 = 4(x – 10) and passes through (–3, 7)? A. y

love history [14]

So, we know the slope of the original equation is 4. So the perpendicular slope is the negative reciprocal, so it's -1/4. Then, the points have to be -3, 7. So when we plug that into our equation, we get

$Y-7 = -\frac{1}{4}(x--3)\\ Y-7=-\frac{1}{4}(x+3)$
