A picture frame consists of two rectangular strips of wood, each having a width of 1 inch on all sides. If the area of the inner light gray strip is 100 in^2, then compute the area of the outer dark gray strip in square inches.

Answers

Step-by-step explanation:

To compute the area of the outer dark gray strip, you'll need to know the dimensions of the inner light gray strip. Since the inner strip has a width of 1 inch on all sides, you can subtract 2 inches from both the length and width of the outer frame to find the dimensions of the inner strip.

Let's denote the length of the inner strip as L inches and the width as W inches. Then, the dimensions of the outer frame would be (L + 2) inches for the length and (W + 2) inches for the width.

Since the area of the inner light gray strip is 100 square inches, you can set up an equation:

L * W = 100

Now, you can find the area of the outer dark gray strip:

Outer strip area = (L + 2) * (W + 2) - L * W

Substitute the value of L * W from the equation above:

Outer strip area = (L + 2) * (W + 2) - 100

You'll need the specific values of L and W to calculate the exact area of the outer dark gray strip.

Answer:

121

Step-by-step explanation:

the square root of 100 is 10

width is 1 inch

so the length of outside is 11inch

11^2=121

Which expression has a value of 36 when x=4 and y=7 A. 2xy B. 2x+4y C. 6y-x D. 12x-2y

Answers

so subsitute
x=4y=7
A. 2xy=2 times 4 times 7=2 times 28=56 not 36
B. 2x+4y=2 times 4+4 times 7=8+28=36 true

the answer is B
the answer is b, because 2x4 is 8, 4x7 is 28 and 8+28+36

98 prime or composite

Answers


A prime number is a number that has no factors except ' 1 ' and itself.

If I can find any factors of 98 besides 1 and 98, then 98 is not prime.

The factors of 98 are  1,  2,  7,  14,  49,  and  98 .

I guess  98  is not prime.
98  is composite.
98 is a composite number, because 98 has a divisor that is other than 1
