Use PEMDAS
P Parentheses first
E Exponents (ie Powers and Square Roots, etc.)
MD Multiplication and Division (left-to-right)
AS Addition and Subtraction (left-to-right)
and |a| = a for a ≥ 0 or |a| = -a for a < 0.
|-4| - 5 · 2(-1 + 3) =-(-4) - 5 · 2(2) = 4 - 10(2) = 4 - 20 = -16
Its 30% because if you take 103 put it in the calculator and divide by 100 you get 1.03 and multiply that time 30 you get 30.9 thats how you find percent
Answer:
h = 84

Answer:
They both have area 4
Step-by-step explanation:
Area of the square:
Area of the triangle:
Using the left-side of the triangle as the base, and the height from the left-side to the bottom-right corner:
We know the length of the diagonal is 
as we are using a centimetre grid, so we can create an isosceles triangle with side lengths 1 and our unknown length, we can then use Pythagorean Theorem to work out our unknown side length.
