Answer:

Option B is correct

$5(8) \div 5+ 3(8)$

Step-by-step explanation:

Given the equation: $40 \div 5+3 \cdot 8$

we can write

40 as $5 \cdot (8) = 5(8)$

$3 \cdot 8 = 3 (8)$

then;

our equation becomes:

$5(8) \div 5+ 3(8)$

therefore, the expression which replace the box to form an equation is $5(8) \div 5+ 3(8)$

Find the value of x help 10 points

MrRissso [65]

Answer:

x = 5.67

Step-by-step explanation:

We are given a right angled triangle with a length of the hypotenuse 8 with the remaining two sides (base and perpendicular) that are equal to each other.

Assuming the two equal legs of this right angled triangle to be x, we can use the Pythagoras Theorem to find the value of x.

$(x)^2+(x)^2=(8)^2$

$2x^2=64$

Taking square root at both the sides to get:

$\sqrt{2x^2} =\sqrt{64}$

$1.41x=8\\\\x=5.67$

Therefore, x = 5.67.

Answer: if you had a circle of radius r, then the 2*radius is equal to the diagonal of the square. So the length of the side is calculated from the Pythagorean theorem since squares have right triangles in them: (2r)^2=2(l^2). Sqrt(2*r^2)=l where l is the length of the side of the square.
