Answer:
7y+26
Substitute the variables for the equations and add.
During week 2, he could type 15 words per minute, at his fourth week, he could type 30. So 30-15=15. He could type 15 words faster on week 4 than he could at week 2.
Let x be the base of the triangle, and
2x + 4 be the height.
One of the ways in solving for the area of a triangle is to half the product of its height (h) and base (b). Mathematically,
A = bh / 2
Substituting the expression for b and h and the given condition for the area,
<em>(x)(2x + 4) / 2 ≤ 168</em>
