area formula is

A=\frac{1}{2}(b1+b2)h

where:

b1 = small base

b2 = large base

h = height

then solve:

A=\frac{1}{2}(2+6)3=\frac{1}{2}(8)3=\frac{24}{2}=12

asnwer: 12 square units

If 2x + 5y=21 and x+y=3, then what is the value of x?
katrin2010 [14]
The answer is D I think
Given the 2 equations
2x + 5y = 21 → (1)
x + y = 3 → (2)
Rearrange (2) expressing y in terms of x, by subtracting x from both sides
y = 3 - x ← Substitute into (1)
2x + 5(3 - x) = 21 ← distribute and simplify left side
2x + 15 - 5x = 21
- 3x + 15 = 21 ( subtract 15 from both sides )
- 3x = 6 ( divide both sides by - 3 x = - 2 → D
X=-2

Question 26 please. will give brainliest
shusha [124]

Answer:

To find how tall he was at the end of the school year, you add his height at the beginning of the year and during the school year. First you should just add the inches.

2 1/4 + 7/8

The common denominator is 8.

2 2/8 + 7/8

2 9/8

3 1/8

Put back in the 5 ft.

So, Jerry was 5ft and 3 1/8 inches at the end of the school year.

Hope this helped! :)

Using exponents don't understand what's 9 cubed and 20 squared how do I do it in expanded form whett
Naily [24]
Expanded form is when you just write it out.

so 9 cubed becomes:

9×9×9

and 20 squared becomes:

20×20

the exponent tells you how many times to multiply that number by itself. so, whenever it asks for expanded form, you just write the number how ever many times the exponent tells you to and multiply them all.
