What is x² + 7x - 30​

Mathematics
1 answer:
Aleonysh [2.5K]3 years ago
6 0

Are you looking for the value of x?

We can complete the square/factor:

x^2+7x-30=0

(x+10)(x-3)=0

By the zero product property rule, we have two equations, x+10=0 and x-3=0.

So the zeroes of x are -10 and 3

Hope this helped. Comment below if this didn't make sense.

how many cubic blocks of side length 1/6 inch would take to fill a rectangular prism with a length, width, and height of 1/3 inc
borishaifa [10]
Volume of one cubic block = (1/6)^3  = 1/216 cu ins

Volume of the prism = 1/3 * 2/3 * 2/3  = 4/27  cu ins

Number of blocks to fill prism  = 4/27 / 1/216   = (216*4) / 27  =  32

What if the following is the sum of both solutions of the equation....
LuckyWell [14K]

answer

D 2

factor

factor the equation x^{2} - 2x - 8 = 0  into (x + a)  and (x + b) so that a + b = -2 and a * b = -8

the two numbers that meet these conditions are a = -4 and b = 2

x^{2} - 2x - 8 = (x - 4)(x + 2)

find solutions

set both (x - 4) and (x + 2) equal to zero to find your solutions

x - 4 = 0

x = 4

x + 2 = 0

x = -2

add solutions

since the two solutions are x = 4 and x = -2, add them together to get your final answer

4 + (-2) = 2

Please helpp i need this doneee :((
egoroff_w [7]

Answer:

w = \frac{5}{8}, v = \frac{21}{2}

Step-by-step explanation:

With given information, we have \frac{TR}{TQ} = \frac{TS}{TP}, so \frac{5}{13} = \frac{3w}{3w+3}, which gives us w=\frac{5}{8}. Meanwhile, we have \frac{TR}{TQ}=\frac{RS}{QP}, so \frac{5}{13}=\frac{10}{2v+5}, which gives us v = \frac{21}{2}.
