Answer:
The value of W is (P-2L)/2.
Step-by-step explanation:
P=2L+2W
-2L
(P-2L)/2=(2W)
(P-2L)/2=w
Answer:
Step-by-step explanation:

Answer:
y = 3x - 7
Step-by-step explanation:
The <em>point-slope formula</em> for a straight line is
y – y₁ = m(x – x₁)
x₁ = 4; y₁ = 5; m = 3 Substitute the values
y – 5 = 3(x - 4) Remove parentheses
y – 5 = 3x - 12 Add 5 to each side
y = 3x - 7
The graph is a straight line with a y-intercept at y = -7 and a slope = 12/4 = 3.
From any one vertex, you can draw a line that is perpendicular<span> to the opposite base — that's the </span>altitude<span> to this base. Any </span>triangle<span> has three </span>altitudes<span> and three bases. You can use any one </span>altitude<span>-base pair to </span>find<span> the area of the </span>triangle<span>, via the formula A = (1/2)bh </span>
