I have to find the length of the angle indicated for the trapezoid

Stels [109]

That is not a trapezoid, it is a general quadrilateral. All 2-dimensional, 4-sided figures have an internal angle sum of 360 (triangles are 180). So if you assume angles P and Q are right, they are each equal to 90 degrees, for a total of 180.
Subtract: 360 - 180 = 180. We know that S + R must equal 180. If you subtract 180 - 65, you get 115, which is obtuse (greater than 90 degrees). This matches the drawing as the unknown angle is clearly greater than 90. So the answer is 115 degrees.

What is the value of this expression? 4/15+3/5−2/3 Enter your answer in the box as a fraction in simplest form.

forsale [732]

Answer:

$\frac{4}{15} + \frac{3}{5} - \frac{2}{3}$

$\frac{4 \times 1}{15 \times 1} + \frac{3 \times 3}{5 \times 3} - \frac{2 \times 5}{3 \times 5}$

$\frac{4}{15} + \frac{9}{15} - \frac{10}{15}$

$\frac{4 + 9 - 10}{15}$

$\frac{13 - 10}{15}$

$\frac{3}{15}$

$\frac{1}{5}$

hope it helps you :)

have a great day

Rewrite the expression using GCF and distributive property. 64x-24

Ede4ka [16]

The greatest common factor between 64 and 24 is 8

Let's divide both terms in the expression by 8 and leave the expression in parenthesis...

Like this!

64x -24

$\frac{64x}{8} - \frac{24}{8}$

8x - 3

Leave 8 we divided outside the parenthesis

Now we have this!

8( 8x - 3)

This is the distributive property form!

Factor 2x^2-4x-30 completely. A. 2(x-5)(x+3) B. (2x-5)(x+3) C. (2x+3)(x-5) D. 2(x-3)(x+5)

OLEGan [10]

Answer:

<h2>2(x - 5)(x + 3)</h2>

Step-by-step explanation:

$2x^2-4x-30\\\\=2\cdot x^2-2\cdot2x-2\cdot15\\\\=2(x^2-2x-15)\\\\=2(x^2+3x-5x-15)\\\\=2[x(x+3)-5(x+3)]\\\\=2(x+3)(x-5)$
