For whatever reason, Brainly questions are often missing the first character. Here, we assume it is A, so that the intended statement is ABCD~EFGH.

FG = BC*(EH)/AD = 15*60/45 = 20 . . . . inches

Answer:

Step-by-step explanation:

Alright, lets get started.

ABCD and EFGH are given as similar.

Hence their ratios of the sides will be same.

It means:

$\frac{AD}{EH}=\frac{BC}{FG}$

Putting the values

$\frac{45}{60}=\frac{15}{x}$

Cross multiplying

$45x = 60*15$

Dividing 45 in both sides

$x=20$

Hence the side FG = 20 in : Answer

Consider the two expressions 4b(b+1) and (2b+7)(2b-8). Compare their values if b=-3, b=-2, and if b=10. Is it true that for an v

Answer:

FIRST EXPRESSION:

- If $b=-3$ , the value of $4b(b+1)$ is $24$

- If $b=-2$ , the value of $4b(b+1)$ is $8$

- If $b=10$ , the value of $4b(b+1)$ is $440$

SECOND EXPRESSION:

- If $b=-3$ , the value of $(2b+7)(2b-8))$ is $-14$

- If $b=-2$ , the value of $(2b+7)(2b-8))$ is $-36$

- If $b=10$ , the value of $(2b+7)(2b-8))$ is $324$

Yes, for any value of "b" the value of the first expression is greater than the value of the second expression.

Step-by-step explanation:

Substitute the given values of "b" into each expression and evaluate.

- For the first expression $4b(b+1)$ , you get:

If $b=-3$ → $4(-3)(-3+1)=24$

If $b=-2$ → $4(-2)(-2+1)=8$

If $b=10$ → $4(10)(10+1)=440$

- For the second expression $(2b+7)(2b-8))$ , you get:

If $b=-3$ → $(2(-3)+7)(2(-3)-8)=-14$

If $b=-2$ → $(2(-2)+7)(2(-2)-8)=-36$

If $b=10$ → $(2(10)+7)(2(10)-8)=324$

You can observe that for any value of "b" the value of the first expression is greater than the value of the second expression.
