1) both have positives signs OR
2) both have negatives signs
Answer:

Step-by-step explanation:
we know that
An isosceles triangle has two equal sides and two equal angles
so
The perimeter of triangle is equal to

Eliminate parenthesis

Combine like terms

Yes it is the same. 1/4 +1/4 = 1/2. so 9/10-1/2=9/10-1/2
The perimeter would be about 34.4 because if you choose the bottom side to be ten, by multiplying 35 by 2 to get 70 you can divide by 10 to get 7. Since you know the height and width, you can use pythagorean theorem, a^2 + b^2 = c^2. Plug in the numbers you have 10^2+7^2=c^2. c^2=149, so if you square root 149 you will get a irrational number but when rounded you get 12.2- so that is one side multiply by 2 and get 24.4- and add 10 to get 34.4
Answer:
Step-by-step explanation:
5.1 × 108 = 550.8
9.6 × 10^0
10^0 = 1
9.6 × 1 = 9.4
2.44 × 10 = 24.4
5.023 × 1010 = 5073.23
