the length of a rectangle is 7 cm more than its width and the area is 30 cm find the length, width and the perimeter

Answers

Answer:

Step-by-step explanation:

let width=x

length=x+7

x(x+7)=30

x²+7x-30=0

x²+10x-3x-30=0

x(x+10)-3(x+10)=0

(x+10)(x-3)=0

either x=-10 (rejected being negative)

or x=3

width=3 cm

length=3+7=10 cm

Perimeter=2(10+3)=2×13=26 cm

Write out the equation in slope-intercept form:

y=-5/3x+6 (Once we know that, it'll be easier to convert it into standard form.)

Subtract -5/3 from both sides of the equation:

y+5/3x=6

Subtract 6 from both sides:

y+5/3x-6=0

Multiply both sides by 3 to get rid of the fraction:

3y+5x-18=0

Then arrange the numbers to x and y are on one side by itself:

3y+5x=18

And that's your answer!

Hina get? Give your answer to 2 dp
HELP PLEASE

Answers

Answer:

$362.64

Step-by-step explanation:

Assuming that "S" represents the money in U.S. dollars, we are given the starting amount as 270 pounds.

We first need to convert the pounds into euros, since £1 = €1.11

So all we have to do is £270 × €1.11 = €299.70

Then, we need to convert euros into dollars, since €1 = $1.21

So all we have to do here is €299.70 × $1.21 = $362.637

Which rounds to $362.64

The following triangle is equilaterial triangle. Solve for the unknown variable.

Answers

Answer:

d

Step-by-step explanation:

Since the triangle is equilateral then the 3 sides are congruent, then

2x = 6 ( divide both sides by 2 )

x = 3

and

3y = 6 ( divide both sides by 3 )

y = 2

Thus x = 3 and y = 2 → d

Okay, so I checked on my calculator, and 5,6, and 7 are right

Step-by-step explanation:

Number 8 would be 45 degrees.  Both of the missing angles would be 45 degrees

Those two lines on either side of the triangle mean both of the angles are the same.

It would be 45° because if you subtract 90 from 180 you get 90 and then divide that by 2 and you get 45

A Sofia made a calculation error.
B Sofia used the length of one of the legs as c when she should have used the length of the longest side as c.
C Sofia does not know if triangle ABC is a right triangle, so she cannot use the Pythagorean Theorem or its converse.
