Solution
To find Which two numbers on the number line have sn
absolute value of 1.75 .
Absolute value means " how far a number is from
zero " .
"1.75" is 1.75 away from zero .
and " -1.75" is also 1.75 away from zero .
i.e
| 0 - 1.75 | = 1.75
| 1.75 - 0 | = 1.75
So , the absolute value of "1.75" is 1.75
similarly , absolute value of "1.75" is 1.75 .
Hence , the two numbers are -1.75 and 1.75 .
Answer:-8x^2-6x+36xy^2+27y^2
Step-by-step explanation:
using the FOIL method
W= width; L= length =w+22m; p= perimeter= 2(L+w)
1616 meters= 2 (L+w) substitute for L
1616m+ 2(w+22m+w) divide each side by 2
808m= 2w+22m subtract 22m from each side
786m=2w divide each side by 2
393m=w Anwer: The width is 393 meters
L=w+22m=393m+22m=415m Answer: The length is 415 meters
If she needs to use 225g of flour for each cake and wants to make 18 cakes she will need 4050g (225x18=4050) of flour but she only has 360g which is obviously not enough flour. For one cake she needs 75g of sugar and since she needs to make 18 cakes she needs 1350g (75x18=1350) of sugar. She only has 135g so it’s not enough.
X^2 - 18x + 81 = 0
x^2 - 9x - 9x + 81 = 0
x(x - 9) - 9(x - 9) = 0
(x - 9)(x - 9) = 0
(x - 9)^2 = 0
x - 9 = 0
x = 9
