What is the value of the expression |-7|+|-4|

Hey there!

Remember this ⬇

~ Negative & negative = positive

~ Positive & positive = positive

~ Negative & positive = negative

~ Positive & negative = negative

So in this equation we will have a POSITIVE since we 2 NEGATIVES

| - 7 | + | - 4 | = 7 + 4

11 = 11

< xcy ≅ < xby

step-by-step explanation:

in δcax and δbax,

so, δcax ≅ δbax (side-angle-side or sas)

since δcax ≅ δbax, we can conclude < acx ≅ < abx

in δacy and δaby,

so, δacy ≅ δaby (side-angle-side or sas)

since δacy ≅ δaby, we can conclude < acy ≅ < aby

now,

< acy ≅ < aby

=> < acx + < xcy ≅ < abx + < xby

=> < acx + < xcy ≅ < acx + < xby   (since < acx ≅ < abx already proved above)

subtracting < acx from both sides, we get

< acx + < xcy -< acx ≅ < acx + < xby -< acx

cancelling out < acx and -< acx from both sides, we get

< xcy ≅ < xby (proved)
