Can someone help me with this

Mathematics
1 answer:
Oksanka [162]3 years ago
7 0

Answer:

20

Step-by-step explanation:

We know that the formula for the area of something is 1/2 * base * height

So we multiply 1/2 * 8 * 2 for The first triangle and get 8

Repeat for the other 3:

1/2* 2*2 = 2

8+8+2+2 = 20

* there are 4 triangles but I only needed to do the formula for two of them because they have identical triangles.

I hope this helps :)

X^2+10x+19=0 complete the square PLEASE EXPLAIN
wlad13 [49]

Answer:

Step-by-step explanation

In the form ax^2+bx+c

a x c should equal two factors of b

However, in this equation

1 x 19 has no factors that = 10

so you must use the Quadratic Formula which is,

x = \frac{-b+-\sqrt{b^2-4ac} }{2a}

so the answer should be

x = \frac{-10+-\sqrt{10^2-4(1)(19)} }{2(1)}

x = \frac{-10+-\sqrt{24} }{2}

x = \frac{-10+2\sqrt{6} }{2}      and    x = \frac{-10-2\sqrt{6} }{2}

The product (x) of two numbers is 24 and their sum (+) is 10. What is the value of the largest of the two numbers?
RideAnS [48]

let the two numbers be x and y

From the first sentence,

xy=24

x+y=10

Then make y in equation 2 the subject of the formular and substitute in equation 1

x+y=10

y=10-x

substituting in equation 2

x(10-x)=24

open the bracket

10x-x^2=24

=-x^2+10x=24

Transfer the constant to the left hand side

=-x^2+10x-24=0

Then factorise completely

What is the distance between (1,-5) and (-3,6)​
Wewaii [24]

Answer:

\large\boxed{\sqrt{137}\approx11.7}

Step-by-step explanation:

The formula of a distance between two points:

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

We have two points (1, -5) and (-3, 6). substitute:

d=\sqrt{(-3-1)^2+(6-(-5))^2}=\sqrt{(-4)^2+11^2}=\sqrt{16+121}=\sqrt{137}
