The diagram below shows a pennant in the shape of an isosceles triangle. The equal sides each measure 13. The altitude is x + 7
Kisachek [45]

Answer: The length of the base is 10.

Step-by-step explanation:

You can draw an isosceles triangle like the one shown attached.

An isosceles triangle has two equal sides. Then, you can divide it into two right triangles, where the base of each one of them will be:

b'=\frac{2x}{2}=x

The hypotenuse of each right triangle shown is 13 and the other legs are (x+7) and x, therefore you can apply the Pythagorean Theorem:

13^2=x^2+(x+7)^2

Simplify the expression:

169=x^2+(x^{2}+2(x)(7)+7^2)\\169=x^{2}+x^{2}+14x+49\\0=2x^{2}+14x-120

Use the quadratic formula, where:

a=2\\b=14\\c=-120

x=\frac{-b\±\sqrt{b^2-4ac}}{2a}

Then:

x=\frac{-14\±\sqrt{14^2-4(2)(-120)}}{2+2}

x_1=5\\x_2=-12

Choose the positive value, because lengths are not negative.

Substitute the value of x into the base 2x. Therefore, the answer is:

b=2x=2(5)=10

Which equation represents the general form of a circle with a center at (-2,-3) and a diameter of 8 units
balandron [24]
Fo a circle with radius, r and center (h,k)
te equation is
(x-h)²+(y-k)²=r²
d/2=r
8/2=4=r
center is (-2,-3)

(x-(-2))²+(y-(-3))²=4²
(x+2)²+(y+3)²=16

If 3(x - 4) = x + 4, then x =8
Greeley [361]

Answer:

Valid

Step-by-step explanation:

3(x-4)=x+4              <em>Given</em>

3x-12=x+4                <em>Distribute</em>

2x=16<em>                      Subtract x from both sides and add 12 to both sides</em>

x=8                           <em>Divide each side by 2.</em>

The elves ate all 327 cookies in a 1/2 hour. What is the rate in cookies per hour?
Elenna [48]
Well.. an hour is.. 60 seconds.. but, 1/2 an hour is.. 30 seconds.. And if the elves ate 327 cookies, you would have to divide 327/100 * 30, and that would be.. 1,090 rates in cookies that they ate per hour! Hope I was able to help! And.. if you can, please give me Brainliest! I would really appreciate it! Merry Christmas, and God Bless you, and your whole family! Be/stay safe, and have a good rest of your day! :)
