The answer to the expression is 28.

Using the steps of pemdas, start off by simplifying the exponent.

-2+4·3²-6

-2+4·9-6

Then multiply 4 by 9.

-2+36-6

Finish off by adding/subtracting from left to right.

-2+36-6

34-6

Find the greatest common factor: 12ab^2c^4 + 20a^4bc^3 + 16a^3b

nordsb [41]

Option A

The greatest common factor is 4ab

Solution:

Given that,

We have to find the greatest common factor

$12ab^2c^4+20a^4bc^3+16a^3b$

First find the GCF of numbers

GCF of 12, 20, 16

The factors of 12 are: 1, 2, 3, 4, 6, 12

The factors of 16 are: 1, 2, 4, 8, 16

The factors of 20 are: 1, 2, 4, 5, 10, 20

Then the greatest common factor is 4

Now find the GCF of variables

$ab^2c^4\\\\a^4bc^3\\\\a^3b$

Here,

ab is the greatest common factor

Therefore, GCF of variables is ab

Thus, GCF of given expression is: 4ab

Which is the same as 10-2? A) 0.0001 B) 0.001 C) 0.01 D) 100

IceJOKER [234]

The correct answer is C. This is because
10^-2 = 1/10^2 which is 0.01

Answer:

Point of intersections are (0, -7) and (5, -2).

Step-by-step explanation:

From the graph attached,

A straight line is intersecting the circle at the two points (0, 7) and (5, -2).

Now solve algebraically,

Equation of the line → y = x - 7 -------(1)

Equation of the circle → (x - 5)² + (y + 7)² = 25 -------(2)

By substituting the value of y from equation (1) to equation (2)

(x - 5)² + (x - 7 + 7)² = 25

(x - 5)² + x² = 25

x² - 10x + 25 + x² = 25

2x² - 10x = 0

x² - 5x = 0

x(x - 5) = 0

x = 0, 5

From equation (1),

y = 0 - 7 = -7

y = 5 - 7 = -2

Therefore, point of intersections are (0, -7) and (5, -2).

Please help me with this!! Number 6 is the problem

artcher [175]

The first two consecutive odd integers are 1 and 3.
The height has to be 3 since the question implies that the height is exceeds the base. So the base is 1. b = 1 cm

The area of a triangle is base*height*(1/2)
Plug in the values for base and height.
1*3*(1/2)

Simplify. Your final answer should be 1.5 cm^2
