First find the area of the triangle,
(8.4 x 24)/2 = 100.8
Then find the area of the parallelogram,
24 x 12 = 288

Then add both,
100.8+288 = 388.8 yd^2

Find the length of side a HURRRY

Olenka [21]

Step-by-step explanation:

Since it is a right-angled triangle,

we have a² + 5² = 13². (Pythagoras' Theorem)

=> a² = 13² - 5² = 144, a = 12. (C)

Cara evaluated the expression below.

s2008m [1.1K]

Answer:

Cara multiplied only 4 and 7 together and did not multiply 4 and 13.

Step-by-step explanation:

Let us evaluate the given expression step by step,

$\frac{4(7-13)}{3} +(-4)^{2} -2(6-2)\\$

We can evaluate this expression in two ways; either by subtracting -13 from 7 and then multiply by 4 or by multiplying 4 to 7 and -13.

$\frac{28-52}{3} +16-2(4)$

$\frac{-24}{3} +16-8$

$-8+16-8=-16+16=0$

Now let us see where Cara made an error. We can see Cara just multiplied only 4 and 7 together and did not multiply 4 to 13.

Therefore, Cara made error in her first step.

Find an equation for the line that passes through the points (-5,-5) and (1,4)

Andreas93 [3]

The general line through (a,b) and (c,d) is

(c-a)(y-b)=(d-b)(x-a)

Here that's

(1 - - 5)(y - - 5) = (4 - -5)(x - - 5)

6(y+5)=9(x+5)

6y + 30 = 9x + 45

-15 = 9x - 6y

3x - 2y = -5

Answer: 3x - 2y = -5

We could put that in slope intercept form,

2y = 3x + 5

y = (3/2) x + 5/2

Answer: y = (3/2) x + 5/2
