Answer:

(5,10)

Step-by-step explanation:

(-10x + 7y = 20)8            -80x + 56y = 160

(8x - 6y = -20)10           + 80x - 60y = -200

                                                   -4y = -40

                                                       y = 10

Plug 1 in for y into the first equation

-10x + 7(10) = 20

-10x + 70 = 20

       - 70  - 70

-10x = -50

x = 5

Factorize: Challenge problem:<br> x^2+19x+78<br> help :)
Trava [24]

Answer:

(x + 6)(x + 13)

Step-by-step explanation:

Given

x² + 19x + 78

Consider the factors of the constant term (+ 78) whuch sum to give the coefficient of the x- term (+ 19)

The factors are + 6 and + 13 , since

6 ×13 = + 78 and 6 + 13 = + 19 , then

x² + 19x + 78 = (x + 6)(x + 13) ← in factored form

Always ? Sometimes? Never <br> Explain
Stels [109]

Answer:

Sometimes

Step-by-step explanation:

Quadrilaterals are shapes with four sides.

This means some quadrilaterals will have 4 equal sides, others will have <em>no </em>equal sides!

There is no rule determining side length equivalence in quadrilaterals. But those may be sub-classified as other shapes.
