Change your ten ones to a single ten
to show the new ten right a 1 in the ten column
2x+5x-4=31
7x-4=31
7x=35
X=5
ST=5x-4= 5.5-4=25-4=21
Answer:
Step-by-step explanation:
We can find y-intercept by substituting 0 for x in the equation.
So, we will have:
y=2*5^0+4=2*1+4=2+4=6
y intercept is 6
Apply a law of exponents. When multiplying you add the exponents:-
2^-3 * 2^x * 2^(x+2)
= 2 ^(-3 + x + x + 2)
= 2^(2x - 1) Answer
Answer:
If a parallelogram has at least one 90 degree angle then its opposite angle is equal and also = 90 degrees.
The 2 remaining opposite angles add up to 180 degrees and since they must be equal, they must be 90 degrees each.
So, we have a quadrilateral with four 90 degree angles and is therefore a rectangle OR it could possibly be a square.
