Distribute the 3 to 4m and 6. this makes 12m-18=12
now add 18 to both sides.
12m=30
now divide by 12
m=30/12

Equation: x² + 10x + 21
<u>Step</u><u> </u><u>1</u><u>:</u> Find two numbers that can add up to 10 and be multiplied to 21. We have: 7 & 3, in the sense that 7+3=10, and 7×3=21. Replacing 10 with 7+3, the equation is now → x² + 7x + 3x + 21
<u>Step</u><u> </u><u>2</u><u>:</u> Get the new equation bracketed → (x² + 7x) (+3x + 21)
<u>Step</u><u> </u><u>3</u><u>:</u> Use 'x' in the equation. For the first part, we have 'x'. x² = x × x so, bring out one x out side the bracket, divide 7x by = 7 → x (x +7). Do the same for the second part by dividing 21 by 3 = 7, and then bringing out 3 from the bracket → 3 (x + 7).
Bringing everything together, we have: x(x+7) +3(x+7) → (x+3) (x+7)

From the given figure

Since XY = 5.1 and XZ = 7.7, then

To find x, use the inverse of cos

Use the calculator to find x

The answer is
Answer:
B. x + 2y = 8 is your answer.
Step-by-step explanation:
So this is what you do:
y = -1/2x + 4 <u>You are going to add -1/2 to the other side.</u>
y + 1/2x = 4 <u>You are going to multiply the equation by 2.\</u>
B. x + 2y = 8 is your answer.
