Write a ratio and a percent for the shaded area.

alisha [4.7K]

HEYA MATE 

YOUR ANSWER IS A.3/10,30%

BECAUSE SHADED SQUARES ARE 6 

AND TOTAL SQUARES ARE 20

THAN APPLY THE FORMULA OF PERCENTAGE.

=>GIVEN NUMBER/TOTAL NUMBER×100
6/20×100

THAN WE GET

30%

THANK YOU

I have been struggling with this for a while lol

Answer:

f(x) = (3x -2)(2x +1)

Step-by-step explanation:

The procedure for factoring expression of the form ...

ax² +bx +c

is to look for factors of a·c that have a sum of b.

The product a·c is 6·(-2) = -12. You are looking for factors that have a sum of b = -1. From your familiarity with multiplication tables, you know ...

-12 = 1(-12) = 2(-6) = 3(-4)

The sums of the factor pairs in this list are -11, -4, -1. So, the last pair of factors, {3, -4} is the one we're looking for.

__

At this point, there are several ways to proceed. Perhaps the simplest is to rewrite the linear term as the sum of terms involving these factors:

-x = 3x -4x

f(x) = 6x² +3x -4x -2

Now, the expression can be factored 2 terms at a time:

f(x) = (6x² +3x) -(4x +2) . . . . . pay attention to signs

f(x) = 3x(2x +1) -2(2x +1) . . . . factor each pair

f(x) = (3x -2)(2x +1) . . . . . . . . factor out the common factor of (2x+1)

If sin(y°) = cos(x°), which of the following statements is true?

Firdavs [7]

Answer:

y = w and ΔABC ~ ΔCDE

Step-by-step explanation:

Given sin(y°) = cos(x°)

So, ∠y + ∠x = 90° ⇒(1)

And as shown at the graph:

ΔABC is aright triangle at B

So, ∠y + ∠z = 90° ⇒(2)

From (1) and (2)

∴ ∠x = ∠z

ΔCDE is aright triangle at D

So, ∠x + ∠w = 90° ⇒(3)

From (1) and (3)

∴ ∠y = ∠w

So, for the triangles ΔABC and ΔCDE

∠A = ∠C ⇒ proved by ∠y = ∠w
∠B = ∠D ⇒ Given ∠B and ∠D are right angles.
∠C = ∠E ⇒ proved by ∠x = ∠z

So, from the previous ΔABC ~ ΔCDE by AAA postulate.

So, the answer is y = w and ΔABC ~ ΔCDE
