Perimeter:

P = 2(W + L)

P = 2(3.5 + 6.5)

P = 2(10)

P = 20 units


Area:

A = WL

A = 3.5 * 6.5

A = 22.75 square units

Could someone help?<br> Thank you
frozen [14]

Answer:

See Below

Step-by-step explanation:

Thankfully, all the parts you need are given.

First, find the surface of one triangle

A = 1/2bh

A = 1/2(15)(9)

A = 1/2(135)

A = 67.5

Multiply by 4 to get the sum of all the sides.

67.5(4) = 270

Now find the surface area of one square

A = bh

A = (15)(15)

A = 225

multiply by 5 to get all 5 sides

225(5) = 1125

Add sums together

1125 + 270 = 1395

How do you do this?????

y = 2x - 9

Step-by-step explanation:

Let's rewrite the given equation such that only y is on the left side and everything else on the right side:

3x + 6y = -30 \Rightarrow 6y = -3x - 30

Simplifying this by dividing by 6, we get

y = -\frac{1}{2}x - 5

This line has a slope of -1/2, which means that a line perpendicular to this has a slope of 2 (i.e., negative reciprocal). So we can write its equation as

y = 2x + b

This is the slope-intercept form of the equation of the line perpendicular to our given line. To complete this form, we need to find the value of b. Since this line passes through (1, -7), put these numbers into our equation to get

-7 = 2(1) + b \Rightarrow b = -9

Therefore, the slope-intercept form of the equation can be written as

y = 2x - 9
