Answer:
4x (x - 2y)
Step-by-step explanation:
Pull out what factors they both have and put it outside the parentheses, put the rest inside after dividing.
Answer:
Option D is correct.
Step-by-step explanation:
It is given that 6 feet tall casts shadow for 38 feet long.
We need to find the shadow f 986 ft tall Eiffel tower.
Let's set up proportional equation to solve. Let the shadow length as 'x' feet for the tower.
Cross multiply,
6 x= 37468
Divide both sides by 6.
x= 6244.67 feet approximately.
If we round it to nearest feet, we get 6245 feet.

let's recall that in an isosceles triangle, the twin sides make twin angles at the bottom/base, so on the triangle on the left-side, if the "vertex" atop has an angle of 116°, then the twin sides below are simply 180° - 116 = 64, split that in half and that's 32° each.
The same is true for the isosceles triangle on the right side. Also recall that a flat-line is always 180°, 32 + 72 + 76 = 180.
Check the picture below.
First question:
The cube root of 626 is a number than, when cubed, returns 626. So, if it is between two integers n and n+1, it means that . This is the case for 8 and 9, since you have .
Second question:
The square root of 52 follows the same principles of the first question, but you have to square the numbers instead of cubing them. So, this time the number lies between 7 and 8, since .
Third question:
To solve this kind of exercises, factor the number under the root, and use the root property . You have
Fourth question:
This exercise is similar to the third one, but again you change the order of the root. So, you have
