The length of the tent's base is
Explanation:
The tent is shaped like an isosceles triangle and measures 7 feet.
Since, isosceles triangle has two equal sides, the two sides of a triangle are 7 feet.
It is also given that the diagonal measures 9 ft.
Now, we shall determine the length of the tent's base.
Let x denote the length of the tent's base.
The image of the isosceles triangle having these measurements is attached below:
Using Pythagorean Theorem, we have,
Taking square root on both sides,
Thus, the length of the tent's base is
Answer:
third choice, 5(x+2y-3)
Step-by-step explanation:
multiply every item in the parentheses by 5.
<h2>(a-b)2</h2><h2>(4t-1)2</h2>
a2 - 2ab +b2
(4t)2 -2ab +b2
16t2- 2×4× 1+1
The third table would be your answer.
I know this because I turned both equations shown into graph form, this allowed me to see what the x-values of 1, 2, and 3 would have for y-values. My graph of both equations is shown in the picture below. (Green is f(x) = x + 4 and purple is g(x) = -2f(x))
Twelve hundred-thousandths is<u> </u><u>ten thousandth greater </u><u> </u> than twenty millionths
Step-by-step explanation:
We subtract the two fractions;
twelve hundred-thousandths – 12/100,000
twenty millionths – 20/1,000,000
We begin by finding the LCM of 100,000 & 1,000,000 which is 1,000,000. Then;
12/100,000 – 20 / 1,000,000 = (120 - 20)1,000,000
= 100/1,000,000
= 1/10,000
