Find the slopes of the three sides.

slope of AB = 2/(-5) = -2/5

slope of AC = -2/(-4) = 1/2

slope of BC = -4/1 = -4

No two slopes have a product of -1, so no two sides are perpendicular.
Therefore, the triangle is not a right triangle.

Choose the number sentence that illustrates the distributive property of multiplication over addition.

patriot [66]

Answer:

Option A

Step-by-step explanation:

5 × (4 + 9) = (5 × 4) + (5 × 9), correct

5 × (4 + 9) = (5 × 4) + 9, incomplete, missing 9 x 5

5 × (4 + 9) = (5 + 4) × (5 + 9), wrong

2/3w - 1/4 = 2/3(w - 1/4)

Rufina [12.5K]

Answer:

No solution

Step-by-step solution:

We are given an expression:

$\frac{2}{3} w-\frac{1}{4} =\frac{2}{3} (w-\frac{1}{4} )$

We have only one variable $w$ so we will make $w$ the subject and solve for it.

$\frac{2}{3} w-\frac{1}{4} =\frac{2}{3} (w-\frac{1}{4} )$

Solving the brackets first to get:

$\frac{2}{3} w -\frac{1}{4} =\frac{2}{3} -\frac{1}{6}$

Taking LCM on both sides to get:

$\frac{8w-3}{12} =\frac{4w-3}{6}$

By cross multiplication:

$6(8w-3)=12(4w-3)$

$48w-18 = 48w -36$

$48w - 49w -18 + 36 = 0$

$w$ gets cancelled so we are left with $18\neq 0$

Therefore, $w$ has no solution.
