Answer:
37.5 cm^2
Step-by-step explanation:
The area of a parallelogram is
A = bh where b is the base and h is the height
A = 7.5 * 5
A = 37.5 cm^2
Answer:
We have that y = 21 when x = 11.
Step-by-step explanation:
We solve this question by proportions, using a rule of three.
Since they vary inversely, we apply the inverse rule of three, that is, with lateral multiplication instead of diagonal.
33 - 7
y - 11
So
Dividing both sides by 11
We have that y = 21 when x = 11.

Step-by-step explanation:
Answer:
Step-by-step explanation
A=-2 and b=5.
To have an infinite number of solutions, the two sides must be identical.
6x+15=-3(ax-b)
Using the distributive property,
6x+15=-3*ax--3*b
6x+15=-3ax+3b
This means -3ax=6x and 3b=15;
-3ax=6x
Divide both sides by -3:
-3ax/-3 = 6x/-3
ax=-2x
Divide both sides by x:
ax/x=-2x/x
a=-2
3b=15
Divide both sides by 3:
3b/3=15/3
b=5
Answer:
12 and 34
Step-by-step explanation:
Start with the bigger numbre of 408. Divide by several numbers, tending to range from 10 and up. I divided by 12 which gave me the answer of 34. Taking that answer, I added 12 which gave me the sum of 46.
Thus, adding 12 and 34 would give my 46 and multiplying them would give me 408.
Hope this helps!
