McKenna was asked to write the following expression in standard form. 3-5(3a+6)3−5(3a+6)

When writing the expression in standard form, McKenna made a mistake.

Step 1 2(3a+6)
Step 2 -6a+(-12)
Step 3 -6a-12
Step}\ 4 3−5(3a+6)

3+(−5)(3a+6)

−2(3a+6)

−6a+(−12)

−6a−12

a. McKenna made her first mistake in Step 2

.

b. The correct expression in standard form is

it should be a and d. lmk if i'm wrong xd

answer: yes, since the line has a steeper rate of change than the exponential the y-values will be greater and they will only intersect one time.

< 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)

hi there!

question 1 answer: p/q can be terminating when q = 5^m * 2^n

question 2 answer: -1 and -1

question 3 answer: -4

question 4 answer: 5/12

hope this : )
