4x2 + 100
4x2 − 40x + 100

Answers

Answer 1
Answer: Answer: 4x² + 40x +100

(2x+10)(2x+10)
4x2 + 20x + 20x +100
4x2 + 40x + 100
Answer 2
Answer:

Answer:

(2x+10)^2=4x^2+40x+100

Step-by-step explanation:

Given the expression

(2x+10)^2

we have to simplify the above expression.

By identity

(a+b)^2=a^2+2ab+b^2

Put a=2x and b=10

(2x+10)^2=(2x)^2+2(2x)(10)+10^2

(2x+10)^2=4x^2+40x+100

Option B is correct.

When you divide a number by a fraction, you should multiply the number by the reciprocal of the fraction. So if you make 1 1/3 an improper fraction you get 4/3. When you multiply 24 by the reciprocal, which is 3/4, you multiply it by the numerator and divide it by the denominator. So
(24 x 3) / 4
72 / 4

In the figure,ABC is congruent to ADC . If the square ABCD is dilated by a factor of 2 to form A'B'C'D', what is the ratio of the area ofA'B'C'D' to the area of ABCD?

Answers

In the figure,ABC is congruent to ADC . If the square ABCD is dilated by a factor of 2 to form A'B'C'D', the ratio of the area of A'B'C'D' to the area of ABCD is 1/2. Since the dilation is by a factor of 2, so the area of the A'B'C'D' should be smaller than the area of ABCD.
