Think of it like your drawing it in your head
in my head i would say 8+4=12 carry the 1 so 7+3+1= 11 carry the 1 then 8+5+ 1= 14 so the answer would be 1,412

Answer:

the answer would be 1412

Step-by-step explanation: Take the '4' in 534, add it to the 878 in your head. Thus resulting in 882. Then add the 30 to this number. After adding 30, you should get 912. Then add 500, and your answer is 1412.

Which Of the following is the solution to 4|x+3|>8?
Shalnov [3]
Too bad you haven't shared illustrations of the possible solutions.

Starting with   4|x+3|>8, div. both sides by 4:     <span>|x+3|>2

Case 1:  x+3 is already positive:  then x+3>2, or x > -1

Case 2:  x+3 is negative:  Then -(x+3)>2, or -x - 3 > 2, or -5>x or x<-5

Draw a number line representing x values.  Place empty circles at x = -5 and x = -1.  Draw a vector from the circle at x = -1, to the right of x = -1.  Draw a vector from the circle at x = - 5, to the left of x = -5.  Note that x values between x = -5 and x = -1 are not solutions.</span>

△ABC is a right triangle. m∠A = 32° m∠B=90°; AC = 9 and AB=5. Choose the expression used to find BC?
Westkost [7]

Answer:

Step-by-step explanation:

The diagram of the right angle triangle is shown in the attached photo.

From the given right angle triangle,

AC represents the hypotenuse of the right angle triangle.

With m∠32 as the reference angle,

BC represents the adjacent side of the right angle triangle.

AB represents the opposite side of the right angle triangle.

To determine BC, we would apply

the Sine trigonometric ratio which is expressed as

Sin θ= opposite side/hypotenuse. Therefore, the expression used to find BC is

Sin 32 = BC/9

BC = 9Sin32
