Answer:

1a the square root of 37

1b the same as a

2 y=3x+2

Step-by-step explanation:

a and b use the distance formula

for number 2 use rise over run to find the slope and find where the line intersects to find the y intercept.

Hope this helps :)

The shorter leg of a right triangle is 7cm shorter than the longer leg. The hypotenuse is 7cm longer then the linger leg. What i

Gelneren [198K]

The shorter leg is 21cm, longer leg is 28 cm and hypotenuse is 35cm.

Step-by-step explanation:

Let,

The longer leg = x

The shorter leg = x-7

Hypotenuse = x+7

Using Pythagoras theorem;

$a^2+b^2=c^2\\(x-7)^2+(x)^2=(x+7)^2\\x^2-14x+49+x^2=x^2+14x+49\\2x^2-14x+49-x^2-14x-49=0\\x^2-28x=0\\x(x-28)=0\\$

Either,

x= 0

Or,

x-28=0 =>x=28

As length cannot be zero, therefore,

Longer side = 28cm

Shorter side = x-7 = 28-7 = 21cm

Hypotenuse = x+7 = 28+7 = 35cm

The shorter leg is 21cm, longer leg is 28 cm and hypotenuse is 35cm.

lara31 [8.8K]

Here you go. Do you think that you could help me with my question

5a – 10b = 45
5a – 10(3) = 45
5a – 30 = 45
+30 +30

Find the distance between (-7,-2) and (11,3)

jarptica [38.1K]

Answer:

The answer is

<h2> $\sqrt{349} \: \: units$ </h2>

Step-by-step explanation:

The distance between two points can be found by using the formula

where

(x1 , y1) and (x2 , y2) are the points

From the question the points are

(-7,-2) and (11,3)

The distance between the points is

We have the final answer as

<h3> $\sqrt{349} \: \: units$ </h3>

Hope this helps you
