Answer:

First picture: 60

Second picture:

Step-by-step explanation:

The first step for the first picture is to find the area of the triangle on top. In order to do that, we have to use the equation: (W*L*1/2)

(3*4*1/2)=6

Then, we multiply the above equation by the Height. Which makes the equation become 60.

The first step for the second picture is the same. We first find the area of the triangle on top.

(12*9*1/2)=54

Then we multiply the height by our above answer.

(54*20)=1,080

The other measurements that were there aren't needed. So, next time, completely ignore them!

Hope you have a good day/night! Good luck!

A line has a slope of 3 and a y-intercept of 5. What is its equation in slope-intercept form? Write your answer using integers,

s344n2d4d5 [400]

Answer:

$y=3x+5$

Step-by-step explanation:

The problem is asking for slope-intercept form, luckily, they gave us both of those things.

Slope-intercept form: $y=mx+b$ , where $m=$ slope and $b=$ y-intercept.

So,

$y=3x+5$

Hope this helps!

10x 6x+8 Solve For X

zhannawk [14.2K]

Answer:

I had x to be 2

Step-by-step explanation:

a square has all it side to be equal

so 10x=6x+8

you will group like terms 10x-6x=8

4x=8 you divide both side by the coefficient of x which is four so X=2

3. if kx² + 2x + k = -kx have equal roots, find the values of k.<br>

crimeas [40]

Answer:

k = - $\frac{2}{3}$ , k = 2

Step-by-step explanation:

Using the discriminant Δ = b² - 4ac

The condition for equal roots is b² - 4ac = 0

Given

kx² + 2x + k = - kx ( add kx to both sides )

kx² + 2x + kx + k = 0 , that is

kx² + (2 + k)x + k = 0 ← in standard form

with a = k, b = 2 + k and c = k , thus

(2 + k)² - 4k² = 0 ← expand and simplify left side

4 + 4k + k² - 4k² = 0

- 3k² + 4k + 4 = 0 ( multiply through by - 1 )

3k² - 4k - 4 = 0 ← in standard form

(3k + 2)(k - 2) = 0 ← in factored form

Equate each factor to zero and solve for k

3k + 2 = 0 ⇒ 3k = - 2 ⇒ k = - $\frac{2}{3}$

k - 2 = 0 ⇒ k = 2
