The length of a rectangle is 20cm longer than its width.
The area of the rectangle is 1000cm?
Find the width and length of the rectangle.
Give your answers in surd form.
[tex]\text{Width} ~= w ~ cm \\\\ \text{Length}~,l = (20+ w) ~ cm \\\\\text{Area of rectangle} = 1000 cm^2\\\\\\\text{Now,}\\\\l \cdot w = 1000\\\\\implies (20 + w) w= 1000\\\\\implies w^2 +20w -1000=0\\\\\\\implies w = \dfrac{-20 \pm \sqrt{20^2 - 4 \cdot 1 \cdot (-1000)}}{2 \cdot 1}\\\\\\\implies w = \dfrac{-20 \pm \sqrt{4400}}{2}= \dfrac{-20\pm 20\sqrt{11}}2 = -10 \pm 10\sqrt{11}\\\\\text{Width cannot be negative so,} \\\\w= -10+10\sqrt{11}=10\left(\sqrt{11} - 1 \right) ~ cm\\\\[/tex]
[tex]\text{And length,}[/tex]
[tex]l= 20+ 10\left(\sqrt{11} - 1} \right) = 20 + 10\sqrt{11} - 10 = 10 + 10\sqrt{11} = 10 \left(1+ \sqrt{11} \right)~ cm[/tex]

Answer:
y = 1/3x +1
Step-by-step explanation:
y intercept is 1 and the rise is one with a run of 3
how do we find x and y intercepts
Answer:
To determine the x-intercept, we set y equal to zero and solve for x. Similarly, to determine the y-intercept, we set x equal to zero and solve for y. ...
To find the x-intercept, set y = 0 \displaystyle y=0 y=0.
To find the y-intercept, set x = 0 \displaystyle x=0 x=0.
y+x=1 2x+y=5 x+y=5 solve
Answer:
x=5-y
Step-by-step explanation:

PLZ HELP…..Are the following set of numbers a Pythagorean triple? 101,20,99
Answer:
Yes, Yes they are. Unless they are supposed to be in the order "20 99101" then they are most definitely a pythagorean triple.
Answer:
Yes, the sides would form a right triangle.
Step-by-step explanation:
[tex]99^2 + 20^2 = 101^2\\\rule{150}{0.5}\\99^2 + 20^2 = 10201\\\\9801 + 400 = 10201\\\\\boxed{10201 = 10201}[/tex]

Find the value of x for which m ll n
Answer:
x=54
Step-by-step explanation:
2x+13=3x-41
-13 -13
__________
2x=3x-54
-3x -3x
__________
-1x=-54
__ __
-1 -1
X=54
I Hope this helped <3
Answer:
x = 54
Step-by-step explanation:
If m||n, these two angles will be equal in degrees

The line would be dotted since it's > not ≥. You would shade above the line since it's greater than, not less than.
You don't need to graph the line to choose the correct answer, but if you would like to:
y - 3 > 2x + 2
y > 2x + 5

Find x.
8x-4=4x+12
Thank you!!
Answer:
4
Step-by-step explanation:
8x - 4 = 4x + 12
Add 4 to both sides:
8x = 4x + 16
Subtract 4x from both sides:
4x = 16
Divide by 4 from both sides"
x = 4

Answer:
Ms. Brown needs 0.18 more cents to afford the pounds of granola and cranberry mix.
Step-by-step explanation:
Ms. Brown = $10 limit
Purchases 1.75 lbs of granola and 2.9 lbs of cranberry mix
Cranberry per lb = $3.25
Granola per lb = $2.19
1.75 x 2.19 = 3.8325 (Cost of granola)
2.9 x 2.19 = 6.351 (Cost of cranberry)
3.8325 + 6.351 = 10.1835 (Total cost of both cranberry and granola)
10.1835 rounded to nearest cent = 10.18
10 < 10.18
Ms. Brown doesn't have enough money to buy the pounds of granola and cranberry mix.
