Answer:
y=(x - 2) squared - 11
Step-by-step explanation:
Answer:
The answer to your question is 4.
Step-by-step explanation:
You take
7 and times it by 4
than you take 8 and times it by 4
Now you take both numbers
28 times by 32 to equal 896
Finally you divide your number by 2. To equal 448.
Here is the formula
Area= Base * Height / 2
:) Hope this helps
Answer: y= -5x+7 hehe its right
Step-by-step explanation:
y=mx+b
y=-5x+7
Answer:
192 is the answer
Step-by-step explanation:
Answer:
56.644 m^2
Step-by-step explanation:
It's a rule that if the ratio of the sides of 2 similar figures is a:b, the ratio of their areas is a^2:b^2. (I may not be using the standard variables or the exact wording here, but that's the basic idea.)
You can simplify this and understand it with squares. All squares are similar, right? Imagine a 2 in. by 2 in. square and a 4 in. by 4 in. square. The ratio of their sides is 2:4, or 1:2. (The ratio of their perimeters is the same thing. 2*4=8 inches for the smaller square, and 4*4=16 for the bigger square. 8:16=1:2) The ratio of their areas is 4:16, or 1:4. (1/2)^2=1/4
The same thing applies here. The perimeter of the larger figure divided by the perimeter of the smaller one is 34/20=1.7. That means that the area of the larger figure divided by the area of the smaller one is 1.7^2, or 2.89. You can write an equation where x is the area of the larger one:
x/19.6=2.89
x=56.644 m^2
