Answer:
Yes
Step-by-step explanation:
The formula for area of a triangle is A = (1/2)bh,
For the first triangle we can leave it in general terms, so it's area is
A = (1/2)bh, depending on what b and h are, but it doesn't matter here...
The second triangle has base that is twice the other triangles base. Bases being multiples of each other is the definition of being proportional so the bases are proportional, an the area of the second triangle is
A = (1/2)(2b)h, which simplifies to
A = bh
Comparing the 2 areas, you can see that one has a multiplier of (1/2), so their areas are proportional
Answer:
9:5 = 1428:x
ratios can also be written as fractions, so
9/5 = 1428/x
solve for x
9/5 × x = 1428
x = 1428 / (9/5)
x = 918
<u>Answer:</u>
The answer is c = 
<u>Solution:</u>
When a sum of two numbers is multiplied by a number, the number can be distributed to the addends separately, then adding the products together will produce the same result as multiplying sum by the number. This property is called distributive property of multiplication.
To find the value of, a(c-b)=d
On applying the distributive property of multiplication which is ![[a\times(b+c)=a\times b+a\times c]](https://tex.z-dn.net/?f=%5Ba%5Ctimes%28b%2Bc%29%3Da%5Ctimes%20b%2Ba%5Ctimes%20c%5D)
Here we get,

So the equation will be,
