The area of the smaller square

Pani-rosa [81]

Hmm, so that means that the diagonal of the square is 8

we draw and get a right triangle

pythagorean theorem
the legs are the same measure since it's a square
the hyptonue is 8
so
remember if the legs are a and b and the hypotnuse is c then
a²+b²=c²

alrighty
a=b
c=8

a²+a²=8²
2a²=64
divide both sides by 2
a²=32
sqrt both sides
a=√32

wait, the area is side times side, but it's a square so it's side² which is a²=32

the area is 32

answer is A

The height of a certain banner is equal to one third of its length. If the banner is 5 ft tall, write the equation that can be u

pav-90 [236]

Answer:

$L=3h$

Step-by-step explanation:

Let height of a banner be $h$ , then we know that this is $\frac{1}{3}$ of the length $L$ of the banner; so we have

$h=\frac{1}{3} L$ .

Now we can rearrange this equation to solve for the length of the banner given it's height:

$L=3h$

So there we have it!

If the banner is 5 ft tall, then it's length will be:

$L=3*5=15ft$

Can somebody help me????

ddd [48]

$f(x)=5x^2-3\\\\\\
f(x+a)=5(x+a)^2-3=5(x^2+2ax+a^2)-3=\\\\=\boxed{5x^2+10ax+5a^2-3}$

On the other hand:

$f(x+a)=5x^2+30x+42$

so:

$10ax=30x\\\\10a=30\qquad|:10\\\\\boxed{a=3}$

Answer C.
