Answer:

Step-by-step explanation:

Factor, where possible the expressions on the numerators/ denominators

3x - 21 = 3(x - 7) ← common factor of 3

x² + 3x = x(x + 3) ← common factor of x

7x - 49 = 7(x - 7) ← common factor of 7

The rational expression can now be written as

$\frac{3(x-7)}{x}$ × $\frac{x(x+3)}{7(x-7)}$

Cancelling the factors x, x - 7 on the numerator/denominator leaves

$\frac{3(x+3)}{7}$ → C

What is the measure of angle of 1?

Ludmilka [50]

Answer:

m<1 = 118

Step-by-step explanation:

The remote angles theorem states that when one extends one of the sides of a triangle, the sum of the two non-adjacent angles is equal to the measure of the angle between the extension of the side and a side of a triangle. One can apply this theorem here by stating that

(28) + (90) = m<1

Remember, a box around an angle signifies that its measure is (90) degrees.

Solve this problem by performing the operation,

118 = m<1

What is the standard form of the equation y=-5/2x-3 ?

butalik [34]

The standard form of an equation is the form where that equation has no fractions and is written in the form ax + by = c.

To get rid of the fractions in y = -5/2 x - 3, we need to multiply both sides by 2. That makes the equation become:

2y = -5x - 6

Now we need to get it into the form ax + by = c. We can do this by adding 5x to each side.
