Answer:
<u><em>W = A/6</em></u>
Step-by-step explanation:
<u><em>Isolate the variable</em></u> by dividing each side by factors that <u><em>don't contain the variable.</em></u>
If we call the number "x" then:
x*25%=21
x*25/100=21
x=21*4
x=84
Hope this helps. :)
Answer:
= 4
Step-by-step explanation:
sqrt 15 = 3.872
to approximate to the nearest whole number (integer), you take the first decimal number which is 8, since 8 is greater than 5, you will add one(1) to the whole number which is 3 to make it 4.
Try this option:
1. the sides of the biggest triangle are 16; x and √(16²-x²); the sides of the smallest triange are x;5 and y. The smallest triangle ~ the biggest triangle. Using the property of the similar triangles:

2. according to the Pyphagorean theorem (in the smallest triangle):

answer: y=√55.
Answer:
50
Step-by-step explanation:
2(3^2+4^2)=
3^2/(3x3) = 9
4^2/(4x4) = 16
9+16=25
so.... rewritten it is
2(25)= or 2 x 25= 50
