Answer:

A = 450 cm²

Step-by-step explanation:

Since the right triangle is isosceles then the 2 logs are congruent , both 30 cm and at right angles to each other.

The area (A ) of the triangle is calculated as

A = $\frac{1}{2}$ bh ( b is the base and h the perpendicular height )

Here b = h = 30 , then

A = $\frac{1}{2}$ × 30 × 30 = $\frac{1}{2}$ × 900 = 450 cm²

Answer:

Step-by-step explanation:

Giving Q was not necessary because you aren't doing P(Q) or anything like that....

Anyways,

$p(x) = x^2 + x +3\\$

Since you're doing p(8), you would replace the x's with 8s.

$(8)^2 + (8) + 3 = 64 + 8 + 3 =75$

So your final answer would be 75.

Answer:

$\boxed{\bold{a+2b}}$

Explanation:

Simplify expression to find its equivalent

Expand $\bold{2\left(a+2b\right): \ 2a+4b}$

= $\bold{2a+4b-a-2b}$

Simplify $\bold{2a+4b-a-2b: \ a+2b}$

= $\bold{a+2b}$

Step-by-step explanation:

20x = 4x +16

16x = 16

x=1

multiply the 2 into the absolute value bars. check if there are negatives. if there aren't, bars can be removed. solve as normal
