Answer:
1. A = 40 units²
2. A = 72 units²
3. B) 45
Step-by-step explanation:
1. This shape comprises 4 congruent triangles with base of 5 units and height of 5 units.
Area of a triangle = 1/2 x base x height
Therefore, area of polygon = 4(1/2 x 5 x 4)
= 40 units²
2. This shape comprises two pairs of congruent triangles.
Area of a triangle = 1/2 x base x height
Therefore, area of polygon = 2(1/2 x 2 x 6) + 2(1/2 x 10 x 6)
= 72 units²
3. Count the number of shaded squares:
9 + 8 + 7 + 6 + 5 + 4 + 3 + 2 + 1 = 45 units²
The complete factor of the expression 
is 
correct option is D.
<h3>What is a factorization?</h3>
It is the method to separate the polynomial into parts and the parts will be in multiplication. And the value of the polynomial at this point will be zero.
The expression is .
To solve the expression properly we have to take common (2x²). Then we have
The factor is .

y = 4x+5 is in the form y = mx+b which is slope intercept form. Anything in y = mx+b form is linear. It graphs out a straight line.
Contrast this with y = x^2 which is nonlinear because it graphs a curve that isnt a straight line. All quadratics like this graph out a parabola which resembles a bowl shaped curve.
Answer:
counting from the left, the number 0 is the second number and it's the number In the unit position
Step-by-step explanation:
The position of number 0 in 10.56 is to be determined by first identifying the llrank of numbers in 10.56
Starting with first
1 : the number 1 is in the ten position
0: the number 0 is in the unit position
5: the number 5 is in the tenth position which is the position immediatly after the decimal.
6: The number 6 is in the hundredth position which is the position after the first number after the decimal
But the counting from the left, the number 0 is the second number and it's the number In the unit position
Answer:
It is a perfect square trinomial.
Step-by-step explanation:
The square of a binomial can be solved like this:
We have the expression:
Then, we consider a and b as:
The solution would be:
