45/45/90 triangles have side lengths leg/leg/leg root2
Here the leg is root 7 and the x is in the hypotenuse so x is root 7 * root 2
Simplifies to root 7*2 = root 14
Answer:
2x-8d
Step-by-step explanation:
<span>to write 8 21/40 as a decimal we need to write the fraction where denominator is a power of 10.
the denominator now is 40, when we multiply 40 by 25, we get 1000.
then the denominator would be a power of 10.
lets multiply the fraction 21/40 by 25 </span>

<span> 8 21/40 is a mixed fraction made of 8 wholes and a fraction that is now 525/1000.
when dividing by 1000, the decimal point that is after 525 should move 3 decimal places to the left, then the decimal point comes before 525.
then 21/40 is equal to 0.525. since we have 8 wholes; 8 + 0.525 = 8.525</span>
The 1.5 pound box of raisins
Convert the 650 grams to pounds and you will get 1.433 pounds which we would round to 1.4
1.5 is definitely greater than 1.4
N! means multiply the number by every number less than n
example 5! means 5 x 4 x 3 x 2 x 1
