Answer:

$18 + 4(m - 3) + 4m \\ 18 + 4m - 12 + 4m \\ = 8m + 6$

Answer:

~ 8m+6

Explanation

~ So first we have to expand the brackets

~ Expanding the brackets we should have: 4 times m and 4 times negative three.

~ Now re write it out: 18+4m-12+4m

~ Collect like-terms now such as all the m’s and normal numbers.

~ Collect all the m’s: 4m+4m=8m. Collect other numbers: 18-12=6

~ And now, you should have 8m+6

Can someone help me with this question please

It’s for sure B the formula for circumference is
Pi times the diameter and the diameter is double the radius so it’s pi multiplied by 8

malfutka [58]

Answer:

Student 2 used the correct steps to construct parallelogram PQRS.

Step-by-step explanation:

Out of all the students, student 2 got all the steps correct.

Fix the compass at Q and draw an arc that intersects side QP.

Without changing the width of the compass, move the compass to R and draw an arc.

Draw a line segment from R that passes through T and intersects the second arc at S.

Which problem matches the given inequality? d > 12.75 Chelsea spent $12.75. Chelsea spent about $12.75. Chelsea spent less th

timurjin [86]

Answer:

Chelsea spent more than $12.75

Step-by-step explanation:

To solve this problem we should understand the meaning of signs first.

sign (<) → less than

sign (>) → more than

sign (=) → equal to

sign (≤) → Not more than

sign (≥) → At least

If the statement is,

"Chelsea spent more than $12.75"

d > 12.75

Therefore, Chelsea spent more than $12.75 is the correct statement.

△WPJ∼△DNJ<br> What is PWPW ?<br> Enter your answer in the box.

Kruka [31]

Use <em>CPCTC</em> and make ratios and proportionalities to find the value of segment PW:

If △WPJ∼△DNJ, then according to CPCTC, WP must be proportional to DN and PJ must be proportional to JN. Now, we can make a ratio:

$\frac{WP}{DN}= \frac{PJ}{NJ}$

Substitute the values that are given in the diagram.
DN=87.5
NJ=56
PJ=64

$\frac{WP}{87.5}= \frac{64}{56}$

Solve for x. You can do it by cross-multiplication.

$\frac{WP}{87.5}= \frac{64}{56} \\ 56*WP=64*87.5 \\ 56*WP=5600 \\ WP=100$

The measure of segment WP is 100 meters.
