Please help me it would mean the world. Extra points!
The answer is 15in^2 provided by my teacher I just need the work.

Step-by-step explanation:

a^2 + 2(b - 6) - 17. a = -7 b = 2

= (-7)^2 - 2(2 - 6) - 17

= 49 - 4 + 12 - 17

= 40

Answer:

623

Step-by-step explanation:

To find the top area of the square=26-15=11

Area of the top square= 11 x 13= 143

Are of the bottom rectangle=15 x 32= 480

Area of both the shapes combined= 480+143=623

Answer:

95%

Step-by-step explanation:

(320 - 15) / 320 x 100 = 95%

Answer:

The algebraic equation would be 3 + x - 4 = 6

Answer:

If s₃ is the length of the 3rd side, the possible values are in the interval.

5 < s₃ < 19

Step-by-step explanation:

For a triangle, we know that the sum of any two sides is always larger than the other side.

So if a triangle has 3 sides:

s₁, s₂, and s₃, we have:

s₁ + s₂ > s₃

s₁ + s₃ > s₂

s₂ + s₃ > s₁

In this case, we know that two sides are:

s₁ = 7

s₂ = 12

And we want to find the possible values of s₃.

Then if we use the above inequalities, we get:

7 + 12 > s₃

7 + s₃ > 12

12 + s₃ > 7

With the first one we get:

19 > s₃

Now we can rewrite the other two as:

s₃ > 12 - 7 = 5

s₃ > 7 - 12 = -5

The first one is more restrictive than the second:

s₃ > 5 > -5

So we can use only the first one.

Then the two inequalities are

s₃ > 5

s₃ < 19

Then the range is:

5 < s₃ < 19

This means that any value between 5 and 19 can be a possible length of the third side (5 and 19 are not possible lengths)

Answer:

no

15 x 8 x 11 is greater than one yard of fabric

Step-by-step explanation:

Volume of a rectangular prism = length x width x height

15 x 8 x 11 = 1320 in^3

1 yard = 36 inches

1320 is greater than 36 inches. she does not have enough yard of fabric

Answer:

36 cm

Step-by-step explanation:

The formula to find the area of a triangle is A=1/2bh where b stands for base and h for height.

So, 8 times 9 equals 72, and 72 divided by 2 is 36.

Answer:

[tex]\huge\boxed{\sf 995.4 in.\²}[/tex]

Step-by-step explanation:

Area of the circle:

= πr²

Where r = 21 in.

= (3.14)(21)²

= (3.14)(441)

= 1385.4 in.²

Area of triangle:

= [tex]\sf \frac{1}{2} (Base)(Height)[/tex]

Where Base = 20 in. , Height = 39 in.

= [tex]\sf \frac{1}{2} (20)(39)[/tex]

= (10)(39)

= 390 in.²

Area of the shaded region:

= Area of the circle - Area of the triangle

= 1385.4 - 390

= 995.4 in.²

Answer:

184

Step-by-step explanation:

V=lwh

(4)(5)(2) = 40

(7)(4)(3) = 84

(2)(5)(4) = 60

40 + 84 + 60 = 184

Answer:

Solution given:

perpendicular [p]=20miles

base[b]=21Mile

hypotenuse [h]=?

we have

By using Pythagoras law

h²=p²+b²

h²=20²+21²

h=√841

h=29miles

he would walk 29 miles on the way back

Answer:

1) 3 miles/h

2) 3 miles

Step-by-step explanation:

6 miles/2h = 3 miles/h

4h = 12 miles

3h = 9 miles

12 - 9 = 3

Answer:

1 is 3 miles an hour and 2 is 3 miles

Step-by-step explanation:

multiply 90 by 54

L times w

Answer:

A   4860 yd²

Step-by-step explanation:

area = length * width

area = 90 yards * 54 yards

area = 4860 yd²

Answer:

11 sq units

Step-by-step explanation:

(6×4) - ½(6×1 + 4×3 + 2×4)

= 24 - ½(6+12+8)

= 24 - ½(26)

= 24-13

= 11 sq units

Answer:

H

Step-by-step explanation:

To find purple, you divide 162 by 3 as there are 3 people who like red for every one person who like purple. To find blue, you need to divide 162 by 3, which is 54, and then multiply it by 9 because there were 9 people who like blue for every person that liked purple.

Answer:

87.92 inches cubed or 87.92 in.^3

Step-by-step explanation:

The base of a cylinder is a circle, so we need to calculate the area of the circle first. The equation for the area of a circle is:

area (a) = pi * r^2 =3.14*2*2 =12.56sq.inches

again,

volume of cylinder = area of the base * the height

= 12.56 * 7

= 87.92 inches cubed or 87.92 in.^3

Answer:

25

Step-by-step explanation:

if X = 4 then you would do

4(4) + 9

since 4 x 4 is 16

add that by 9

16 + 9 = 25

so the value of 4x + 9 = 25
