Part A:
The opposite of finding the square root of a number is finding the square of a number.

square root of d = 10
d= 10^2
d=100

Part B:
The opposite of squaring a number is finding the square root.

X^2=144
X=the square root of 144
X=12 or -12

I hope this helps! Please comment if you have any questions.

n = 5(10) + 10
n = 50 + 10
n = 60

f(x) = -2x + 7 plug the -5 in for x
f(x) = -2(-5) + 7
= 10 + 7

In the diagram line p is parallel to side BC. What is the sum of the measure of angle 1 and angle 2? What is the sum of the meas
Masteriza [31]

Answer:

m<1 = 57°

m<2 = 74°

Step-by-step explanation:

m<1 = 57° (alternate interior angles are congruent)

m<B + m<C + m<2 = 180° (sum of interior angles of a triangle)

57° + 49° + m<2 = 180° (substitution)

106° + m<2 = 180°

Subtract 106° from both sides

m<2 = 180° - 106°

m<2 = 74°

SpyIntel [72]

Answer:

= 1700 :)

Step-by-step explanation:

-multiply all the sides,

-add them,

- then double the answer (or times it  by 2):

1) 30 times 20 = 600

30 times 5= 150

20 times 5 =100

2) Add them:

600+150+100 = 850

then times 850 by 2

850 times 2 = 1700

What is the LCM of x^2+5 and x^2+10x+25?
avanturin [10]

Answer:

(x+5)²(x²+5)

Step-by-step explanation:

Given two functions x²+5 and x²+10x+25, to get their Lowest common factor, we need to to first factorize x²+10x+25

On factorising we have:

x²+5x+5x+25

= x(x+5) +5(x+5

= (x+5)(x+5)

= (x+5)²

The LCM can be calculated as thus

| x²+5, (x+5)²

x+5| x²+5, (x+5)

x+5| x²+5, 1

x²+5| 1, 1

The factors of both equation are x+5 × x+5 × x²+5

The LCM will be the product of the three functions i.e

(x+5)²(x²+5)

This hives the required expression.

How is the graph of f(x)=-3x^2-4 different from the graph of f(x)=-3x^2 ?
-BARSIC- [3]

Answer:

B

Step-by-step explanation:

rules:

add outside the function : f(x) ± a;  will shift  a + up / a- down

add inside the function: f(x ± a); will shift a + left  / a- right

so if

f(x)  becomes f(x) -4  will be shifting down 4 units
