Answer:
WV = 42
Step-by-step explanation:
Δ UVW and Δ XYW are similar ( by the AA postulate ) , then the ratios of corresponding sides are in proportion, that is
=
( substitute values )
=
( cross- multiply )
15 WV = 630 ( divide both sides by 15 )
WV = 42
If she already gets the first two, thats a given 100% situation. then it is just 1/4

Answer:
8x² + 6x - 35
Step-by-step explanation:
A = (2x + 5)(4x - 7)
Front: 2x * 4x = <em>8x²</em>
Outside: 2x * (-7) = <em>-14x</em>
Inside: 5 * 4x = <em>20x</em>
Last: 5 * -7 = <em>-35</em>
Add up: <em>8x² - 14x + 20x -35</em>
Simplify: 8x² + 6x - 35
