Answer:
4x+y=−3
Step-by-step explanation:
simplify −4(x+2).
Apply the distributive property.
y−5=−4x-4⋅2
Multiply −4 by 2.
y−5= --4x−8
Move all terms containing variables to the left side of the equation.
4x+y=−3
The Pythagorean theorem can be used to find the length (c) of the diagaonal given the two side lengths a and b.
c² = a² + b²
c² = (50 ft)²(4² +3²)
c = (50 ft)√(16+9) = 250 ft.
Clare travels 250 ft when she rides across the lot diagonally.
Let's say, the total sales is "x"... .so hmm on Plan A, he gets 350 plus 7% of "x", well, 7% is just (7/100) * x or 0.07x
now, on Plan B, he gets 436 plus 5% of "x", 5% of "x" is (5/100) * x, or 0.05x
he's better off with A, only if A is greater than B, namely,
A > B
and surely you know how much that is.
Check the picture below.

since the width is just a dimension unit, it can't be -31.
what is the length? well, the length is w + 30.
Answer:
22
Step-by-step explanation:
if a=15
then, 2(a-5)+2= 2(15-5)+2 = 2(10)+2= 20+2=22
