PLEASE HELP IMAGE ATTACHED!!! the area of this parallelogram is 120mm^2. Find the value of X

Marta_Voda [28]

The area of a parallelogram is the base times the height so:

A=bh, in this case:

A=hx

x=A/h, we are told that A=120mm^2 and h=10mm so

x=120mm^2/10mm

x=12mm

An expression is given.

Katyanochek1 [597]

9514 1404 393

Answer:

Step-by-step explanation:

Maybe you want to evaluate ...

16 - 14 ÷ 2 + (3 +2)²

The parentheses are evaluated first.

16 -14÷2 +5²

Then the exponential term.

16 -14÷2 +25

The division is evaluated next.

16 -7 +25

Finally, the sum is evaluated.

= 9 +25

= 34

Question 8 options:

prisoha [69]

Answer:

Step-by-step explanation:

Based on what you have here as the slope we can set the slope formula equal to 34 using the points (0, 8) and (8, c) to solve for c, then use the points (0, 8) and (a, 5) to solve for a.

c first:

$\frac{c-8}{8-0}=34$ and

$\frac{c-8}{8}=34$ and

c - 8 = 272 s0

c = 280

For a:

$\frac{5-8}{a-0}=34$ and

$\frac{-3}{a}=34$ and

-34a = 3 so

$a=-\frac{3}{34}$

That seems a little weird, but when you plug those points into the slope formula to solve for the slope, it works out the way it should.
