-2x+x-4=-7 , -1x=-3, x=3. y=3-4, y=-1
Answer:
190 cm2.
Step-by-step explanation:
First you have to find the area of the whole shape.
20 cm times 10 cm is 200 cm2.
Now, you have to find the area of the smaller shape inside.
5 cm times 2 cm = 10 cm2.
Finally, you subtract the area of the smaller shape from the larger shape to find the area of the shaded area.
200 cm2 - 10 cm2 = 190 cm2.
Answer:
yes it is
Step-by-step explanation:
Answer:
See explanation below.
Step-by-step explanation:
No.
The distance between 19 and 15 is 4. Both numbers are positive, 4 units apart.
The distance between -19 and -15 is also 4. Both numbers are negative, 4 units apart.
When you find the distance from 19 to -15, keep in mind that one number is positive, 19, and one number is negative, -15. The two numbers are on different side of zero on the number line.
Start at -15. -15 is 15 units to the left of zero. To get to 0, you need to go 15 units right. Now you need to go from 0 to 19. That is another 19 units right. Add 15 + 19 to get 34.
The distance from 19 to -15 on a number line is not 4. It is 34.
Answer:
<em>PZ = 15</em>
Step-by-step explanation:
<u>Similar Triangles</u>
Two triangles are similar if all of their corresponding side lengths are proportional to the same scale factor.
It's given triangles TPR and XPZ are similar, thus we can find the scale factor by comparing two corresponding sides with known lengths.
Sides TR and ZX are corresponding and the proportion of their side lengths is 15/9. The same proportion must be satisfied by the sides TP and XP:
PX and PZ are congruent, thus:
Calculating:
PZ = 15
