Answer:

Option (c) is correct

The factors of  the given equation  4x^2+20x+25 are =\left(2x+5\right)(2x+5)

Step-by-step explanation:

 Given equation 4x^2+20x+25

We have to find the factors of given equation and chosoe the correct option.

Consider the given equation  4x^2+20x+25

Rewrite 4 as 2²

and 25 as 5²

We have,

=2^2x^2+20x+5^2

Apply exponent rule, a^mb^m=\left(ab\right)^m

we have,

=\left(2x\right)^2+20x+5^2

rewrite 20 x as \mathrm{\:as\:}2\cdot \:2x\cdot \:5

we have,

=\left(2x\right)^2+2\cdot \:2x\cdot \:5+5^2

Apply algebraic identity \left(a+b\right)^2=a^2+2ab+b^2

We have,

=\left(2x+5\right)^2

Thus, The factors of  the given equation  4x^2+20x+25 are =\left(2x+5\right)(2x+5)

10g - 4 (g - 2) + 11 = 1
sergij07 [2.7K]

Answer:

g = -3

Step-by-step explanation:

10g-4(g-2)+11=1

1) 10g-4g+8+11=1  Combine like terms

2) 6g+8+11=1

3) 6g+19=1

4) 6g=-18   To continue the process of getting the variable by itself, we have to get rid of 19. So we are going to subtract 19 from 19 to get 0, and whatever we do to the other side, so we subtract 19 from 1 to get -18.

5)6g=-18    To get the variable by itself, instead of mutiplying, we will divide by 6 on both sides to get... g=-3! Hope this helps!

weqwewe [10]

Answer:

The reflexive property of congruence allow us to say that RST = RST .

Option (C) is correct .

Step-by-step explanation:

Definition of Reflexive Property of congurence

The meaning of  Congruence is  figure has the same size and shape. If you were comparing something to itself, then it definitely have the same size and shape this is called Reflexive Property of congurence .

By using Reflexive property of congurence .

RST = RST

Therefore reflexive property of congruence allow us to say  that RST = RST .

Option (C) is correct .
