Answer:

Answer:

let base side be x=AB=BC

by using Pythagoras law

h²=p²+b²

(√8)²=x²+x²

8=2x²

x²=8/2

x=√4=2=AB=BC

Step-by-step explanation:

sin BAC=BC/AC

<BAC=sin-¹(2/√8)=45

Question:

Given a polynomial f(x), if (x − 4) is a factor, what else must be true?

_______________________________________

Solution:

f(x) is a polynomial.

(x - 4) is a polynomial of f(x).

By converse of factor theorem: If (x - a) is a factor of f(x), then, f(a) = 0.

On comparing (x - 4) with (x - a), we get,

So,

f(a) = 0

=> f(4) = 0

Answer:

  J  3/4 cup

Step-by-step explanation:

Step 1: read and understand the question.

  The question is giving you amounts of flour and 2 types of sugar.

  The question is asking for a difference between two quantities:

Step 2: determine the relations you need to use to solve the problem

   You need the combined amount of sugar, which you find by adding the quantities of each of the kinds.

  3/4 cup white + 3/4 cup brown = 6/4 cup sugar combined

 You need the difference of that quantity from the quantity of flour, which you find by performing subtraction:

  flour - sugar = (2 1/4) - (6/4) . . . . cups

Step 3: Use your knowledge of arithmetic.

  (2 1/4) -(6/4) = 9/4 -6/4 = (9 -6)/4 = 3/4

Step 4: Answer the question that was asked.

  The difference between the flour and sugar amounts is 3/4 cup.

Answer:

y = -1/5x - 1

Step-by-step explanation:

The line crosses the y axis at -1, making it the y-intercept.

Since the line is going downwards from left to right, we know that it is a negative slope.

The line goes down one and 5 right. That makes the slope -1/5.

The equation is y = -1/5x - 1

Answer:

1 - x-axis, 2 - y-axis, 3 - y-axis, 4 - x-axis

Answer:

I think she has about 3 segments for sprinting and 6 segments for jogging

Answer:

Step-by-step explanation:

Left side

4x + 2x - 10

6x - 10

Right side

6x - 12

Eventually when you equate these sides, you will get an absurd answer because the 6x term will be subtracted out on both sides

that means you get -10 = - 12

which destroys the whole concept of equality. There is no solution.

Irene offered answer equivalent to the original expression

Given :

Mrs. Crosland asked students to factor the expression 28x - 8

The student are given some expression . To find correct expression , we need to factor the given expression

[tex]28x-8[/tex]

Both 28 and 8 are divisible by 4

Lets factor out 4 from the given expression.

When we factor out 4, then we divide each term by 4

[tex]28x-8\\4(\frac{28}{4} -\frac{8}{4} )\\4(7x-2)[/tex]

The students offered the answers shown

Carlos: 2(14x - 4)

Danny: 7(4x - 1)

Irene: 4(7x - 2)

Answer:

∠ABC = 54°

Step-by-step explanation:

an inscribed angle is 1/2 the size of an incenter angle.

so:

∠AMC = 2(∠ABC)

10x - 12 = 2(4x + 6)

10x - 12 = 8x + 12

simplify:

2x = 24

x = 12

∠ABC = 4(12) + 6 = 54°
