Step-by-step explanation:

-3x - 10 > 14

-3x > 24 (add 10 to both sides)

x < -8 (divide by -3, flip inequality sign)

The missing step is -3x > 24.

Identify the GCF of 6x^2y^2 − 8xy^2 + 10xy
myrzilka [38]

Answer:

The GCF for the numerical part is 2

Step-by-step explanation:

6x^2y^2-8xy^2+10xy

It contains both numbers and variables, there are two steps to find the GCF(HCF).

1). Find the GCF for the numerical part 6, -8,10

2). Find the GCF for the variable part x^2,y^2,x^1,y^2,x^1,y^3

3).Multiply the values together.

Find the common factors for the numerical part:

6,-8,10

Factors of 6

6: 1,2,3,6

Factors of -8

-8: -8,-4,-2,-1,1,2,4,8

Factors of 10

10:1,2,5,10

Common factors of 6,-8, 10 are 1,2

The GCF Numerical=2

The GCF Variable= xy^2

Multiply the GCF of the numerical part 2 and the GCF of the variable part xy^2, and you'll get 2xy^2

Guys, please help me faster will receive a Brainliest award if you answer my 2 of the math questions with the best given answers
Zolol [24]

Answer:

<u><em>Question 10.</em></u>

Length of the side of the square = \sqrt{441} = 21

By Pythagoras' Theorem,

Hypotenuse = \sqrt{21^{2} + 20^{2} } (H > 0)

                     = 29 m

Ans: 29 m

<u><em>Question 11.</em></u>

By Pythagoras' Theorem,

Length of longer side of 42 km = 42- \sqrt{18^{2} - 15^{2} } (L > 0)

                                                                     = 32.050 km (5 s.f.)

By Pythagoras' Theorem,

Length of the unknown side = \sqrt{32.050^{2} + 15^{2}  } (L > 0)

                                               = 35.4 km (3 s.f.)

Ans: 35 km
